thanks friend!
Its all about having the right tools and skills. Greasless compound it one of the coolest things I ever used. Its crazy to think that a big tube of rubber stuff can be applied to a cotton wheel and take off A SHIT TON of metal! that cuts down on a ton of time.
the only stuff I hand sanded was some of the tight places that I couldnt get a felt bob and my air diegrinder into.
