I came across the stuff, it is used for keeping plastic trim on cars looking good. Despite the name it works on all color plastics. If your plastics start getting the white clouding from lots of scratches or the are just looking old and tired...this is the stuff for you. It's about $10 a bottle and you apply it with a simple clothe. Rub it in like lotion, Absolutely amazing stuff.

Here are some before and after pics. This is all scratches from my boots on the plastics above and behind the motor.
