Hi Walt---Nice to hear from you. I bought the kit about 15 years ago, thru Eastwood, and it was a really great purchase. It included the 4 different grades of grit that I mention in the previous post, and three 6" diameter buffs, that mount on a standard bench grinder. The buffs come with different sized plastic hub bushings to accomodate whatever shaft size the grinder has. The coarsest buff is made from sisal, and is quite aggresive and is used with the emery grit for smoothing really rough stuff. The medium buff is a spiral sewn cotton, which is used with the less aggresive grits, and the third buff is a loose cotton buff, for the final polishing using the white rouge. The kit comes with an instruction booklet which tells what buff to use with what compound. This kit is for use on large peices that can be picked up and manually presented to the buff wheel mounted on the grinder. There are smaller buffs available for getting into small corners like on an aluminum wheel or an intake manifold, and they are generally driven by a flexible shaft which attach to the bench grinder, however I don't have that set-up.
My kit gives very satisfactory results, and the grit sticks (for lack of something better to call them) last a long time.
