I have a set of fog lamps that have ur traditional off white, yellow-ish color. Id like to paint the lens a more blue color to make them match my headlights. Im lookin for input because they get pretty hot after running them for awhile. Is there a specific paint that might due the job? Im not too worried bout losin a lil brightness. oh, and the lens is glass not plastic, thinkin that will factor into the equation. ideas???
