I have done nitorcellulose laquer so I know that one. There is also spirit varnish, varnish, and shellac. Then tung oil and true oil fits in there somewhere. I am almost ready to finish a ukelele and I am working on two mandos. I would like to try something different on the uke so that I will have more choices that I have some experience with when I start finishing the next mando. Ain't this stuff fun??
