One word - ICE. That new car wax ICE. It does an excellent job at brightening up everything it's put to. Clean with a bar, then use the ICE. There are several RV parks in my area, plus just a ton of TT's, etc - everyone is using it to get rid of the dulling that the UV rays causes, and much to everyones suprise, it's doing a great job. I have an old dull trailer that I am planning to do in the next couple weeks. By the way, they are using the clear liquid not the paste wax.
