Having trouble removing paint from metal chairs that my mom gave to me. I began by using sandpaper...a lot of elbow grease not much paint removal. I then tried a scraper well it was actually a wood chisel Again, better but not a lot of progress. I then got out my hand grinder and took the wire wheel off my bench top grinder and used it...lots of flying debris!!!! Still removal was better (not fantastic) but I'm not able to get in the small corners. I do have a rotary tool but the small sandpaper cylinders don't seem to work very well. Maybe once the arms and other long tubular parts are taken apart it will be easier to remove the paint? I have thought about using a sandblaster (I don't own one, maybe I could borrow?) I've thought about using a chemical but not sure which would be the best bet. I really need to take apart the furniture because the bolts are rusted and have strange square nuts May end up cutting the bolts off if I can get between the furniture and the nuts. Anyone have any ideas??? I've attached pics.
