Re: chrome vs pvd coating
I work for the world's largest PVD coater. Nooooo waaaay would I get PVD coated wheels. Yeah, it can be a decorative coating but that's on display parts and pieces, firearms, trophies, etc. I watched a video of how one of these companies does this. Spray a grey primer on and let it cure before PVD coating? No way. PVD coating is only a few microns thick. Any thicker and it can delaminate. PVD coating must have a clean and etched surface for proper adhesion. When we etch tools in our coating vessels, we actually burn a molecular layer off of the tools so the PVD coating adheres properly. Any oil-based solvent like WD-40 will lift PVD coating right off the part. Takes a while to do it but it will do it but it will happen. PVD coating is a line of sight process that occurs in a vaccuum greater than outer space. It would be next to impossible to get a uniform coating thickness in all the nooks and crannies of a complex wheel. I wouldn't do it.
