LOL Paul... you're really reliving your childhood... BB guns and finger painting.
Wes, unless you plan on reshaping the stock, you shouldn’t need to do too much sanding. I use citrus strip to remove the old finish, it does a pretty good job. Then I just lightly sand the entire stock with a 320 grit sandpaper to smooth it out. I’m getting ready to tackle my QB Chief stock, let me know when you are ready and we can do them at the same time.
