No matter how clean and acetoned the rattle can stuff chips off with ease. I may start a paint thread. One question I have is...before hauling the boat project to the dump (never again) I purchased a gallon of high end bilge paint. I think it's one part epoxy. I was thinking, a paint designed to hold up well in a nasty greasy oily boat bilge might make a good paint for a metalworking machine? I have a 4hp oiless compressor (California Air 14cfm) and decent quality spray gun I bought for that project.
