This is a picture of my setup and a close up of the compound.
Load up the wheel; you know you have enough when it starts hitting you in the face! and GENTLY work the loose cotton wheel in all the hard to get places. The best success was when used with the die grinder on the small tips, works wonders in small areas that would normally require tons of fakin' around. As you can see the stuff I got was 320 grid, they are also available in 80 and 180 but I don't really see any need for it.
