Which clear coat is the easiest to apply and produces a smooth, even finish on acrylic artwork?
When it comes to clear coats for acrylic artwork, there are several options available that can provide a smooth and even finish. One popular choice is a spray-on clear coat, specifically designed for artists and craftspeople.

Another alternative is using a two-part epoxy resin, which can offer superior durability and a glass-like finish. Resins are self-leveling and provide a thick, protective layer that is resistant to scratches and yellowing. However, working with resin requires proper ventilation and careful application, as it can be tricky to achieve a bubble-free finish.
Ultimately, the choice between varnish and resin depends on your desired finish and level of protection. It's always a good idea to test different products on a small sample piece before applying them to your entire artwork.
