January 16, 20251 yr On a frame-up restoration, anybody have the frame and swingarm powder coated? Tough finish but difficult to touch up scratches later?
January 16, 20251 yr It's commonly done. Touch up is really not necessary unless it's a show bike. Only downside is that the "paint" (it's really a plastic) is very thick. It can obscure the stamped VIN, and diminishes clearance to parts that are a tight fit. It also must be removed for any electrical connection to the frame (but that's true of paint too).
January 25, 20251 yr I’ve had nylon coated parts, much less susceptible to peeling than powder which always seems to come off in sheets once chipped. Otherwise paint is easier to touch up.
January 26, 20251 yr I had not heard of nylon coating. This link gives a good comparison: https://latem.com/blog/choosing-a-coating-nylon-coating-vs-polyester-coating What is normally termed powder coating (polyester) is thermosetting, whereas nylon is thermoplastic. From my own experience, power coating has been the toughest of paints -- even more so than a 2-part epoxy. I have no DIY experience with power coating, but "coming off in sheets" sounds like inadequate surface prep. My vendor always starts with grit-blasting. I was also advised that only a few powder-coated colors are actually tough. I've only needed black, but special colors require a clear coating on top.
