20 Best Sound Deadening Material For Boat Engine (2023 Updated)

Took a chance on this product to reduce road noise caused by deteriorating very ruff chip coated road surfaces and the Korean tires that came on our 2017 Santa fee. One coat did not get much improvement but two additional heavy coats especially applied to the under body of the car did the trick.

Used a total of 10 cans. Easy to apply and dried in a reasonable time frame with little lasting odor. Seams durable after several days of dry time but not hard to remove over spray with a little WD 40.

Would buy again and fully expect when I replace these tires with a premium product this will be one quiet ride on any reasonable road surface. Money well spent.

Im not sure what Im going to use it for but this spray is really good for filling in cracks. youll need many coats if you plan to spray a vertical surface since it flows like warm ice cream. asphalt mats are still the way to go but Id like to think this product has its place.

Used to spray on wheel wells on 2015 Hyundai Sonata, very noisy tires and road noise. After spraying wheel wells noise was reduced significantly. Ordered 2 more cans to spray trunk area. Was surprised how much it helped.

Removed all 4 wheel well liners and sprayed both sides. If you do this you will need 1 can per wheel well.

This sound deadening material is pretty good and reasonably priced. Works well to deaden sound through door skin and floors. Hard to work with if using large pieces and if you use it while warm, It softens and sticks to itself and everything you don’t want, if you are not careful.

Once it is stuck it is NOT coming off without a fight! Have not used the other brands of sound deadening material so I can’t tell you if it is better or worse. I originally bought this brand because of the low price.

Getting kinda of expensive now, like everything!.

Rockmat is way better then dynamat at a fraction of the cost! Rockmat is 72mil thick and dynamat extreme is only 44mil thick which means it will provide better sound deadening quality then dynamat. Rockmat is exactly like dynamat except rockmat is thicker.

With rockmat, you get a ton more then you would if you bought dynamat. I highly recommend rockmat to anyone wanting to sound dead anything. Its extremely sticky, and will stick to pretty much anything.

Well worth the money spent! I bought the 50 square foot roll, and it comes with a high quality roller. Why spend your kids college fund on dynamat when you can buy rockmat with what you have in your pocket!?.

I recently started applying the material in my Volvo S60. I had the front seats and carpets out so I started with the floor pan area. When tapped the thin metal would “ring” before application. After application the area felt more solid, and would only give a “thunk” when tapped with a knuckle.

Also working on the trunk area, same thin metal, so I expect to reduce road noise and improve subwoofer bass after application. There will probably be some leftover material to apply to the rear deck, you get your money’s worth with Rockmat.

The paper backing peels easily and product adhesion is excellent. The roller is handy to flatten large areas and press the material for best adhesion. Be sure to clean the areas to receive Rockmat well, I used cleaner(like Simple Green), water, a brush and a wet vac to suck out the dirty water.

If you enjoy music in your car, what better way to improve the experience than to make the cabin more quiet. Rockmat will help you make it happen.

Bought this book for my 5 year old granddaughter as she is really interested in learning about the planets. She really enjoys reading this book

I was asked to build a custom copper sink for a client with an historic home. I considered approaching the fabrication from several angles and settled on making a 20oz. copper pan that would be hammer formed to facilitate the water draining efficiently.

I felt that some sound deadening and added stiffness to the copper would only improve the quality of the sink but my testing did not identify a material or adhesive that would give me that and withstand temperatures approaching 212 degrees.

The advertisement for this product convinced me to give it a try. The Damplifier Pro was easy to cut and apply even over a slightly domed surface. It added stiffness to, and quieted the copperwork nicely.

I was careful not to let the bare aluminum edges of the product contact the copper anywhere, avoiding galvanic reaction. I was happy to have found this product and will keep it as an option for future applications.

I had never installed any kind of sound dampener before, but found it very easy with Second Skin. The material cuts smoothly and has stayed in place since installation. My door panels no longer rattle and I am able to bump my stereo at louder volumes without being annoyed.

People also don’t slam my doors as hard as they used to, due to the extra weight. The Door Pack (13. 5 sq ft) was enough to thoroughly cover all four doors of my Camry plus the inside of the fuel door, with one full sheet left over.

Definitely worth the hundred bucks.

I recently remodeled my kitchen. I ordered a copper sink. And while I was waiting for it to be installed I had an epiphany that it might be very loud after it is installed. Since it is close to my family room, I figured my husband would think I was playing drums in the sink during all his tv time.

So I choose your product because it seemed the most efficient and easiest to apply. And I was absolutely correct. A breeze to apply and it did a remarkable job at dulling the sound. Don’t even notice any sound.

BUT, that’s not the end of the story. I had a new fan/vent put over the stove. Mine vents outside. So we were happy it should be so easy to replace. Then a couple days after it was installed, it started to rain.

really hard. i live in Florida and it was a downpour. And along with that was this banging coming from my hood. I thought it would come right through the walls. Soooo what should we do about this?? My suggestion was, Can we put some of the extra pieces of skin on the outside of the vent on the roof?? So we did! And it solved the problem, at least so far.

My question to you though, is there anything that I can paint over the skin with so as to protect it from the Florida sun to give it longer life? So thank you for your amazing product. I tell everyone about it! Blessings,cat.

I ve tried other cheap brands like Kilmat,noico and siless and this blows it out of the water not only does it weigh a ton of bricks but it basically silenced my cab and made my sound system sound a lot better even at low volume so I don t have to worry about turning it up.

I will say that you might want to wait for a warmer day as it does get pretty stiff when cold so I suggest using a heat gun and a roller if it s going to be below 60. Also make sure that you clean off the area very well or it will not stick.

I recommend cutting it in half because trying to mount a single she is very hard as they are very big and heavy. My loud ass truck now sounds like a Bentley, jk but definitely more quiet. I highly recommend this over the other brands.

Worth every penny.

I recently installed this product in my 94 Toyota Land Cruiser. I completely gutted the car and installed from tailgate to firewall, all doors and rear quarter panels. The difference was Amazing! This is the first time I have installed sound dampening and this product is easy to use.

The improvement in sound quality is very noticeable. I researched different products before pulling the trigger and glad that I found Sonic Electronix. You cannot go wrong with this stuff. My Land Cruiser restoration took a major step forward in terms of road noise and sound quality.

Doors sound solid when closing them, and even the door handles quit sounding tin-like when opening the doors.

This has got to be the best value anywhere. I recently completed the install in my entire 94 Land Cruiser. Huge reduction in road noise and a major improvement in sound system quality. I started to notice smaller noises that I had never heard before.

A significant improvement to the restoration process. The doors sound solid when closing and the door handles dont sound tin-like as they did before. The best improvement to a vehicle that unfortunately nobody but myself will notice, but I would do it all over again.

Cut this single 18″x32″ sheet into pieces to dampen two car doors. Obviously not enough material to 100% cover the panel surfaces, but by “pinging” the surfaces and strategically applying Dynamat I was able to dramatically reduce unwanted resonances.

This stuff is expensive for what it is, but when applied strategically you can make a little go a long way.

Great sound proofing with less layering. I put this on my hood to sound proof my engine compartment. It was easy to put on with maximum sound deadening. It surprised me because I figured that I needed a lot more to get the results I was searching for.

Thanks.

Great product! It really works on my 2002 suburban sub woofer issues. After installation, I never heard any vibration in the cargo section except the good quality of bass itself. I definitely would recommend this Dynamat product.

This is an excellent product: easy to apply, less costly per square foot than other perhaps more established products, and highly effective. I’ve used it in a 1993 Volvo wagon, which was like a rolling steel barrel for road noise.

One 75 sq ft pack spread over the rear wheel wells and rear quarter panels was sufficient to make a dramatic reduction in road noise. Same for my 1996 Caprice Classic wagon, although it took more material: about 100 sq ft.

I’ve also used it in a 1996 Cadillac Fleetwood to improve sound quality of the stereo system with excellent results.

The 50 sq ft box of Kilmat sound deadening mat was perfect to line the inside walls, back door, wheel wells and roof of my 159 inch wheel base, high roof Ram Promaster cargo van (100% coverage is not required).

The product is easy to work with including cutting some smaller pieces to fit sections where a full 1 sqft mat would not fit. Installation is easy. peel the backing, stick the mat on the sheet metal then use a roller to fully adhere the mat to the surface.

The inside of my van no longer sounds like you are inside a steel drum when you knock on the metal surfaces. The product works!.

I was visiting a friend who is a custom car builder and we were talking about sound deadner he wanted to show me three cars he had in the final stages and all three had Kilmat installed. He stated Kilmat was the easiest to use, best buy on the market, and was a quality product.

I took his advice purchased the Kilmat and am glad I did. Good Stuff. Gene Hall Crossville TN.

The install was great, peel n stick. And it stays stuck. Easy to trim to fit around obstructions before and after the paper was removed. I’m hoping this will lower the interior temps this summer. Quieter will be a bonus.

I bought Noico 150 mil for my 1975 Ford F-250 firewall. So far it has decreased the temp 20 degrees! It is easy to work with. I like that it comes in smaller squares which make it simple for going around curves.

I decided not to get a custom fit package. I cut pieces to fit. Covering the floor, roof, small sections to deaden sound in the doors. Still had left over. Use tin snips/metal sheers to cut this stuff, VERY easy.

Clean the blades frequently w brake cleaner and they will keep cutting smoothly. Measure twice, cut once and test fit EVERY piece prior to removing the backing. I love this stuff!.

Spent 5 afternoons measuring, cutting, and fitting Dynamat to the inside floor of my 1952 Chevrolet Styleline Deluxe 2-door sedan. I drove the car the other day without carpeting. I can already tell the difference in improved sound.

The orange paint marks the seat belt bolt holes.

Its the same material as Dynamat. No sense in spending twice as much for essentially they same thing. The button texture makes it easy to know how thorough have applied it. I recommend a roller and a heat gun or hair dryer for application.

Super easy and fantastic sound dampening from outside noises and rattles.

It went on really easy just took a little time, haven’t been able to drive my car yet but it sounded really solid when you tap it with your knuckles. Can’t wait to drive my car to see if it helped seems like it will though.

After years of taking the cheap way out wit competing products I decided to try Xtreme based upon reviews. The difference is astonishing! Even with a very basic installation covering only my doors and floor.

Firstly it is much thinner and more flexible (and thus easier to install) but once applied actually performs better. After the first success I applied it over the competitions product on my other car and it quieted the car so much more than the original did, normally a second layer is a waste of money but the competition had been so ineffective.

Next thing I noticed is no stink, no asphalt stink, no musty stink, nothing! Amazing product at an amazing price!.

Dynamat is one of the most recognised names in sound deadening. and to be fair that is because they deliver a quality product. If you buy a box of Dynamat you know that it will be a good CLD material that deadens sound as it should and it will not have any problems with being flimsy, not sticking, sticking for a while but eventually coming off or worse melting on a hot day etc.

However it is pricey for what it is; and compared to other brands. Most brands do a CLD and there are plenty that are perfectly fine for less money. There are even some China imports that are near half the price and I believe they perform well.

‘I believe’ they do anyway. I doubt I will ever use them. Dynamat is one of the most expensive CLD’s to buy. but I am putting it in a brand new WRX. it is sort of product that you know will work well; and you cannot have (and absolutely refuse even the thought of!) a massive failure and a mess to clean up and redo.

Peace of mind is worth the few extra dollars. This is a review of Dynamat so I won’t say too much. but if I could suggest that people make sure they understand what a CLD is and what it does! Say compared to a decoupled MLV layer or a CCF layer or a combination or even OCF may be appropriate.

You have done it wrong if you put tonnes of Dynamatin your car for sound proofing but none of the others.

“install dynamat first and leave the noise behind” – Well. Let’s be honest now. This is advertised as a cure all for sound deadening, and being that it’s so widely praised by all the big names in the custom car industry, I thought I’d bite the bullet and buy the expensive bulk kit so I might finally make my Citroen 2cv quiet at high speed.

If I’m honest with myself though, it hasn’t made the slightest difference where sound deadening is concerned. What it has done is made the doors close with a much more satisfying thump, it really does help there, and knocking on the bonnet makes a much better sound then it did before.

After all though it’s still as loud as it ever was, even with 10 kilos of this stuff in there. I suppose it might make more of a difference in something like a van, where the interior space acts as much more of an echo chamber than any car, but it hasn’t worked for me.

This is a great product by the way if you want to reduce vibration, no question there, but it’s strongly advertised as sound insulation and that it most definitely is not. I’m being told I should have put what they call closed cell foam underneath the bonnet if I wanted to silence the engine, and I’m tempted to go that route now, I know dynamat makes that too, but I won’t be overspending on their version of it after this disappointment.

100 miles down the road from when I installed it and I can confirm that this is a grossly overhyped product and it probably won’t help you in whatever civilian application you intend it for.

used it under the hood of my 2021 toyota tacoma. The instructions were a little miss- leading on weather I could use it under the hood or not. In some of the instructions I read , it stated that it could be used under the hood.

In another section it said not to use it. I did and it works fine. It sustains the heat to keep it from penetrating to the hood , and hopefully stop the paint on the hood from getting too hot and causing the clear coat to possibly blister.

It’s good stuff and sticks well but it’s not particularly easy to work with. I found the sheets a little too big. Yes you can cut it down, but it does add more time. I found the ideal size to work with around A4 paper size.

Anything bigger at it just tries to crease up and it’s difficult to get it to lay flat even when using multiple tools to roll it down. Lined my entire floor and wheel arches in my van.

I have used Fat Mat, MESA, Dynamat and another no name sound deadening product in the past. The Noico gives comparable results at a much lower price. The embossed diamond pattern flattens as you apply it giving visual confirmation that it has been rolled / stuck down.

The foil backing is thin and can be cut easily with too much pressure at the edge of the roller, but all the products I have used were the same. It sticks to contours well and gives a solid sound to the vehicle.

Large sheets are nice for covering big areas but can be easily cut down when trying to fit in a door. Box cutter / razor knife is essential.

Nice high quality deadener. Just make sure you have some big scissors to cut with, otherwise your pointer finger is going to get shredded from the foil. Significant change in the resonance on my panels and they are noticeably quieter.

I deadened the left side of my car and didn’t do the right side for lack of time and I’ve been riding around with the right side plain sheet metal with no plastic trim, and the left side deadened and with plastic trim, and there is a noticeable difference between the two when driving.

Can’t wait to put my 18 in, I’m gonna need more for the doors and to finish the back!.

It isn’t the type of material that I was used to working with when I built large trucks for a living so I was a bit inundated at the roll and stickiness/pliability of it. Living in AZ I realized that doing the install, would be best done in the mornings when the temperature is lower.

That said, I did the install in the morning and was quite amazed and very pleased the the ability of the material to fit the tiny nooks and crannies that would be more difficult if not impossible with What I worked with before.

I did the whole Jeep GC in a time that allowed me to have the whole interior reassembled and the car driveable by the time the temperature would have been uncomfortable and messy. The results are great.

My 21 year old Grand Cherokee is now quiet and I can hear all of my music from Bach to rock and far beyond. Quiet passages are more distinct and the crescendo moments really rock the house because the music has no background noise to distract from it.

I am happy with price and value and would/will use this material again if I do another vehicle.

My 1999 Corvette has loud exhaust on it, really loud. I like it that way but not on the inside of the Corvette when cruising the highway. So this winter I wanted to tackle the sound deadening project.

I had quite a bit of B-Quiet materials left over from when I did my 2002 Corvette back in 2003. I figured I would at least see if it was any good. Sure enough, the materials were like new. I had about 60 sq ft of the Ultimate and 3 sheets of L-Comp.

I used almost all 60 sq ft in the hatch alone so I ordered another 50 sq ft. I could not tell the difference between the 17 year old Ultimate vs the new Ultimate. You can be CONFIDENT in the fact it will be good in your car a very long time.

Anyhow, I used another 25 sq ft of the Ultimate and 2 sheets of the L-Comp. BIG difference in the interior sound level. I can actually hear the stereo now, lol.

I got a 50′ roll of the B-Quiet Extreme for an old 1st generation 4Runner I was fixing up to help eliminate some of the road noise associated with older 4×4’s. I used it on the front doors, inside and outside and could instantly tell a huge difference in the drive noise as well as the modern like quiet “Click” as the doors close versus the 25 year old rattling “Thud” I was used to hearing.

I was so impressed with the product that I have since ordered another 3 rolls for the same vehicle and will be doing the entire interior, firewall, roof, etc as well as installing it in any future vehicles I plan on having.

The added sound quality and retention of sound by the stereo system is unbelievable, even with the 4Runner’s top off. You can blow hundreds of dollars more on “Name Brand” products, but I can guarantee you that you’re just throwing money at a name.

B-Quiet may not spend thousands on marketing or be at every car show, but their product is high quality, easy to work with and install (no heat guns or asphalt garbage), and gives you the results you expect.

I absolutely love the stuff.

I’ve used only dynamat throughout the years so I am not going to comment on how much better it is compared to others. It has never came off even after install vertically. Makes my tinny toyota door sounds like lexus door.

Yes you pay for the brand and reputation, but you also know they will very unlikely compromise by using dodgy and toxic material to uphold their reputation Cost 30% more than local brand, which is fine.

If it’s 50% more, I would likely look at local brands.

This is a very straightforward product that just works, and it works very well. Laws of physics do still apply though, so it helps to have at least a basic understanding of acoustics in order to maximize its effectiveness.

I really like the thickness of this stuff. It is thick enough to be effective, but not so thick that it is hard to apply. I have been experimenting with different applications for this stuff, such as appliances, with great results.

I am looking forward to buying more so I can continue to lower the overall dB level in my life, and at this price it won’t break the bank. Love it.

Came with a few scratches and even with a proper roller, one needs to be careful to not put more into it. The black coloring is very thin. The way that they fold this into the shipping boxes, makes it challenging to get a smooth look.

Need to get really warm to roll out the pattern. Too warm and it tears. So thin that it does not really quiet things down like purpose made soundproof material, unless you have a vibration. I used it for more of a heat deflector than actual sound deadening.

I wish it was even thicker. Anyways, I hope this helps. Thanks for reading.
