I know this is not XR related so maybe it will get deleted or moved but I know you guys are very knowledegable. I was recently given a 72 CB450 that I'm going to part out. It's been sitting in a barn for 27 years so it's got it's share of rust and corrosion. What's the best way to get some of the metal parts restored so I can put them on ebay? I heard theres a way to make an electrical /chemical bath setup. I was wondering if there's any kind of small sandblast gun setup I can atatch to my air compressor. Any ideas?
