Some speakers I picked up awhile ago have metal plinths/stands that the speakers sit on top of. For whatever reason, they had rust problems and the original black paint was peeling esp in the rusty spots. I want to strip the paint off and re-paint them. I used a scraper on the worst parts (where paint was already bubbling up) and the paint came off pretty easy, but in other spots, the paint is stuck on pretty good. I tried to apply some mineral spirits and use both a green scouring pad as well as some course sandpaper for metal, but both seem like they'll be extremely slow going. Any suggestions on how to get the paint off most easily? Or do I need to really strip off the paint off areas where it's not clearly rusted? Since they sit under the speakers and aren't really prominent visibly, I don't feel the need to get them perfect cosmetically, but I don't want the rust to continue progressing and affect any new paint job I put on them. Welcome any advice from the community.
