Santo, you can shoot XIM clear primer over chrome and then use the paint of your choice. It will hold up just about as well as paint over primed bare metal.

The history of powder coating begins in the late 1940s and early 1950s, at a time in which organic polymers were still being spray coated in a powder form on to metallic bases. Dr. Erwin Gemmer, a German scientist, developed in those days the fluidized-bed process for the processing of thermosetting powder coatings, and registered an appropriate process patent in May 1953.

I stand corrected on the word "Invention" Joey, but I do know Australians developed the process commercially way back in the sixties and exported the technology & the equipment to USA.
The finish must be removed for the powder to adhere and bake in. The surface is usually prepared by glass/sand or media blasting, and no parts that can melt at 450 degrees can be left attached, grease, rubber mounts, etc. Even the oil from finger prints can ruin the final finish.
Hope that helps.

You could sand well, scuffing the surface properly, and apply Dupont's mid-coat adhesion promotor, which is clear and perfect for doing away with all sorts of adhesion worries. Of course, we already knew you'd clean the areas very well and remove or tape-off unpaintable areas.

Thanks. Gotta say that I'm getting replies on another board, from people saying that they have done powder over chrome and the powder loves it. Also some saying they use clear powder coating over chrome regularly and that if the chrome plating is intact, it works great.
