What Mike said, and use SEM Trim Black paint, it is self-etching and will adhere to chrome even if you do not rough it up. Self etching paint is what was used originally and what people use on the grille, tail light grilles and the like with good results.I wouldn't worry about trying to remove it. By the time you blast it enough to take the chrome off, you will damage the potmetal. I would just blast it enough to clean it and etch it a little. Thats all I did with mine.
