Will have 4 new steel rims on Wednesday, weather cooperating. I'll need to paint these things. Not sure how to prep them so the paint bonds well. Just a rattle can job. Any suggestions on paint, Rustolium and such?
I strongly recommend etching/sealing primer first. After that do watcha like. Otherwise they will rust up inside and cause air leaks eventually. I don't think enough people use water traps on their compressors.
