A friend posted photos on another forum last summer of his new refrigerator-white Tundra, asking if there was a way to change the color of his chrome grill and bumpers. He felt (and most of us agreed) with all that jewelry it was trying to look like a more expensive vehicle than it already was. It wasn't a good look to him, but he'd gotten a tremendous deal on the truck - one he couldn't pass up. So he improvised.
After some discussion with our more dedicated modification and detailing experts, he decided to live with the white and bought a few cans of Plasti-Dip and after careful cleaning and masking, he sprayed the bumpers and grill in a matching shade - then he carefully applied a top coat of clear Plasti-Dip to match the glossy finish of the rest of the truck. The result was stunning! It looked like a factory job and was a perfect match to the (Frigidaire) white applied to the rest of the vehicle. At last report a month or two ago, it was still holding up well - although he doesn't offroad or otherwise abuse the vehicle. As he reported about the end of last year, he isn't worried about nicks in that coat, if they happen he can always peel it off and spray it again.
If I ever have my old beatervan repainted, I'm seriously spraying the vinyl front and rear bumper covers with Plasti-Dip. It's sure cheaper than paint, and it stands up to far more abuse than the standard-issue vinyl paint with a plasticizer.
