So I have read that you can fix things like uneven surfaces by sanding the top layer of resin, and adding a fresh one to the top. I’m just wondering if that will work for my situation. I have a layer of resin over a vinyl print out, which must have gotten an air bubble under the vinyl. So there is a part of the resin that is raised where the bubble is (if that makes sense). If I sand the top layer and add a new one to even out, would that work?
