If the stock is oil soaked I start with an acetone bath, followed by a bath of denatured alcohol.If no oil soaking is present I use chemical strippers such as citrus-strip, zip strip etc followed by whatever the directions call for to neutralize the stripper. I try to only sand the bare minimum amount and always when the metal is in the wood. I try to not use anything below 240 grit and always use backers for my paper. Good luck!

What's the need for the follow-up alcohol bath? I've always just stopped after the acetone bath and had no problems.
