How much will it take off? You're not getting answers because the question doesn't make sense. It'll "take off" as much as you put time into it. No sh*t.

Sorry but you stepped off the deep end first and used the classic "new guy first post... Reply = "Search button".
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.
