Have you considered ceramic coatings? The coating is not "Chrome" but it's aluminum and ceramic particles in a coating which is heat treated. It's used for side pipes. I coated my side louvers and they look more "Chrome" than the photo above which is discolored. Of course it's not chrome. It can be polished to a high luster which can be close to chrome finish. The look is more like polished aluminum. It's an inexpensive approach to "Chrome plating".
