I have a 2004 Chevy Avalanche, and all of the black plastic trim on the exterior was fading and appeared "chalky". I don't want to fork out the cash for something called "Gator Black" which supposedly returns the cladding to factory condition. I picked up a bottle of Mother's "Back To Black", and WOW am I impressed. The first picture is of one of the wheel flares before I treated it. All of my black plastic looked identical. The rest of the pics are after the Back To Black application. It only costs about 6 bucks!!!

I don't know about long term durability, but this stuff gets my two thumbs up for initial quality.

Looks fantastic!
