I have an old Remington walnut stock that is battered, beat and chipped. I would like to refinish it for a new project that I have in mine. This project I feel I can do about 90% of it myself. So what is the best way to strip the old finish off so I can sand out most of the nicks and dings. I started sanding it but without a power sander, sanding by hand is tough plus the finish gums up the sandpaper very quickly. There's got to be a chemical that will remove the finish and most of the stain if not all of it. HELP!!
