Man I can't even touch that price Frank! Is it with the Lake Country pads and backing plate?
You don't really need all those polishes with the Porter Cable you listed. I would just go with the Optimum Polish and Optimum Compound for your polishes. So you can take off the Poorboys SSR2, and 3. The Pro Polish is a good all around polish. It can be used on plastic,paint,chrome,stainless,etc...so you still might want that.
The Red Moose and Vanilla Moose will work. You can actually mix them together to make Pink Moose too.
You talking about a Gallon of Spray & Gloss?
