Working on a partscaster body, I decided to build with shellac and then switch to tru oil for an outer shell. Having never worked with shellac, I was excited to learn something new. Read the forums and how-to guides, watched the YouTube vids...nobody ever said "don't wet sand the shellac. So I got it looking beautiful, then though I would do an easy wet sand with 400 grit before switching to tru oil. BAD BAD BAD! Do not wet sand shellac! The finish got all cloudy and blotchy. I tried to fix it with denatured alcohol, just made it worse. Tried rubbing in more shellac, no dice. So I just spent a few hours with a bag of rags and some denatured alcohol rubbing off most of the shellac. Lesson learned. Starting over. Do not wet sand shellac!
