Thanks again, Simon, for keeping me out of trouble.
Jon, that is a killer guitar body. Thanks for sharing your experience and suggestions. Sanding sealer might be a good option. As I've said before of my experience with nitro (in a spray can), I could not get the smooth gloss I was looking for, but I kinda like the textured finish I ended up with. This one probably gets poly.
It takes a lot of sandpaper to smooth out the havoc a hoof rasp creates. It's looking pretty good, though.
