My son recently purchased a very hard-played Taylor that has a couple of issues. It's an Academy 10e, so it can only be a few years old. The main cosmetic issue is picking damage below the soundhole. This model came without a pickguard and we'd rather not put one on. At first, we were going to just leave it alone, but since the spruce is completely exposed, we thought it best to put some type of finish on it to keep it from getting worse. The Taylor website states they have used a UV-cured polyester-based finish for the last several years so that is what this instrument has applied to the top. What type of brush on finish could we find locally that would be compatible with that. We'd like to lightly sand the whole top and apply a finish without having to remove every bit of the existing finish, so we're looking for something that will play nice with what's already there.
