I painted the front section of my powder coated frame and the paint didn't stick. I cleaned it with lacquer thinner and then used a base/clearcoat auto paint. After a week it could be peeled off with your finger nail. I'm in the process of stripping it now.
Years ago I painted a tow truck wrecker assy that came from the factory primed and I applied a product called XIM and then the acrylic enamel paint. It held up great. Has anyone tried a similar product or have advise? Thanks
