Looking great Mike, cant see why you couldnt powder coat them at all, but if its got any bubbles/spots/blisters (not flaking though) in the chrome it will be the equivilant of rust/corosion in the alloy that needs to be stopped first, I saw a show on one of the car shows about a re-chrome company and how they fixed the old alloy pock marked trim, they basically drilled out the little pock marks to clean metal and filled the holes by melting the same type of trim material back into the holes and dressing it back, in you case, id be drilling any of the marks out and putting some sort of filler in there otherwise after you powder coat them they will still continue to grow over time,,,,, thats only if you want to go to that effort.
whats next on the list of big steps on Cuda? engine and exhaust? or interior?
