The title sounds like I had a bad Friday night. So I am in the process of trying to remove layers of old paint off a piece of pine furniture that my mom left to me. I am using chemicals because I don't want to ruin any of the wood. The top couple layers came right off with no issue. I am down to a green color probably from the 70's that the chemicals will not take off. Is there another type of chemical that might work or am I forced to sand it?
