I had a M-1 GARAND stock someone had painted . It looked like epoxy paint it was that thick and I removed it with a paint on paint remover. You paint it on , wait , scrape paint off, repete if neccesary, as many times as needed , when you are happy with the results you wash it with water from the hose and let it dry. The hosing down with water and drying seemed to bring out a few little crush marks in the wood, a light wipe down with very fine steel wool finished it out to a rough but quite usable stock that wasn't painted and even had some grain in the wood.
