Did the graffiti remover damage the underlying paint on the body of the car? The same thing happened to my car, and I have a can of lacquer thinner, but maybe that would work better? Did you wipe it off all by hand or use a pressure wsher?
The graffiti remover was only used on the wheels. We used lacquer thinner on the body of the car. We did it entirely by hand with microfiber towels. The spray paint removal probably took 25 man hours.
That looks fantastic. Great work! Mine hasn't been stolen yet, but I might have to do that bumper and trim treatment because my 2006 bumpers have all gone grey and splotchy.
