The GPR I bought a few years ago looks to have some pretty nice wood hidden under the factory finish, but I have a few questions about the job. I've redone a lot of M1/1903/etc stocks with great results, but they only had an oil finish, so denatured alcohol and a little sanding did the job without using any strippers. What do I need to remove the factory finish on my rifle, and how much wood do I lose in doing so (if any)?
