Yes, yes...I know its on an import. But the important thing here is the quality of the rust/patina. I've used plasti-dip on wheels with great results, and I never thought of using to match my old cab/front to my "new" bed. I'm going to have to order some 'dip and experiment. Best part is that it's no commitment; Don't like the results...peel it off!
They even Fauxtina dipped a VW!
