I have claybarred mine twice in the last year. Zymoled it four times. Washed it God knows how many times..
I stopped using anything on my vinyl top, I found most dressings kept it moist for 2 days then dried it out after that. Anyone have any suggestions?
As for my wheels, every month I used the Mothers polish with the powerball attached to the cordless grill.
I *try* to clean up the engine bay every so often, usually when I clean the K&N filter.
As for a degreaser, I use Brake Kleen.. nothing better to get rid of any old leaks or gummed up surfaces.
