powder coat over chrome
#5
I powder coat over chrome practically every business day. The chrome must be media blasted first to etch the surface and identify any loose areas. Once any loose chrome has been removed and feathered out it's on to standard cleaning, pre-treatment, masking and powder. If any loose chrome is not identified before going in the oven to cure the powder the loose chrome will blister.
BTW - Your parts may look like the chrome is perfect, and they may even be brand new, but until they are media blasted you can't tell if any of it is loose.

Gators05 - I see the pic was taken before putting the pipes into use... no carbon inside the ends. I have not had much luck with any textured powders on heat shields and have stopped offering it to my customers. Smooth finishes work fine but the textures tend to discolor or flake from the heat, especially around the head and/or clamp brackets.
jbt - You are sure to have premature failure of your powder coat due to adhesion problems if you don't prep the surface properly. The finish may LOOK good, but let a stone, sand, or hard bug smack it a few times and you're liable to get chipping. If you don't mechanically scuff the surface of chrome I strongly recommend a chemical wash appropriate for the type of metal your are using, i.e. iron or zink phosphate.
