my dad does this at the toyota dealer on dale mabry, but what they offer isnt a change of color, but a clear tape on for the front end all over, from bumper, to hood, to fender, its to prevent your car from chiping with rocks, and bugs, etc etc, and then you peel it off, and bam paint is still fresh, and car looks just as shiny if not better with the 3m clear tape on.

but my dad hates doing it
