I understand physics rather well. I guess the answer I was looking for was something along the lines of "80 grit greaseless on a spiral sewn wheel with light to medium pressure, for 20-30 seconds on a work area will remove aprox how deep of a scratch.
Sorry if I got off on the wrong foot.
Anyway. I received my order yesterday. and the stuff is amazing. I used the 80 grit stuff on a spiral 6" wheel, and used a hairdryer to speed up the layup time on the greaseless. A single application cut down the bare casting on the intake manifold plenum with surprisingly light pressure. in about 5 minutes I covered about a 3X6" area before I had to reapply. I was blown away at how much material it would remove, and yet how flat and smooth it left the surface. in about half an hour I did the entire plenum in 80 and then hit it with the 120. The 120 finish appeared to be what the results of a 220-3X0 grit sand paper would yield.
So far so good, ill post up some pics tonight.

Hi Krazy Kid,
I'm also new to polishing, and want to polish my rough cast motorcycle engine cases. I understand the principles, but how do you use the "hairdryer to speed up the layup time of the greaseless". Any advice would be appreciated, and which grit compounds did you use after the 80 grit greaseless?
Thanks, Magicrat
