I have a couple of custom bikes with polished engines. Pain to keep polished, but I got this kit (Pimp Stixxx) for hard to get to spots and it works great! I have been using it for several years and just thought about using it to get to hard to clean/ wax places on my pinball machines. Works well to get to areas you normally have to strip the topside to get to. Be glad to see others ideas as well.image-145.jpg
