RE: Thinning Clear
 

The auto paint store is really the best place to get everything you need to sand/cut/buff. Perfect-it works pretty good. The old school method is to use 3 stages of compound, Super duty, medium, and a final with a foam polishing pad. The Perfect-it is made to do the work of all 3, I have some and it works good, but seeing that I am old school I still use the more labor intensive method.
