I only know about powder coating from posts on forums and have no actual experience at the process. Are these Model A bumperettes powder coated with real chrome or do you think its just a silver powdercoat being advertised as chrome? Thanks....Michael Pawelek
From watching them do it I would say that is a type of ceramic coating. When it comes out of the oven it is gray and is polished in a tank of viberating ceramic beads. It is what the rod and racing guys use on the headers, it dosn't turn color with heat.
You may be talking about two different processes. Powder coating and ceramic coatings, like Jet Hot. Neither are chrome. Powder coat won't last on headers
Those bumperettes are just silver colored powdercoat. It can't be polished to a shine. They didn't even file out the rust pitting to make them smooth. They just took the easy way out instead of properly polishing and filling the pits and nickel / chrome plating them.
Eastwood makes a reflective chrome powder coat. It is not chrome. I have some here but have not tried it yet so I can't say how good it is.
