YEA! I know about the soap on hot aluminum intakes. and I have tryed the mag wheel cleaner, with bad result, maybe the aluminum was to hot then also.

could a clear type sealer be sprayed on a high temp aluminum block?

my problem is that when I look at a car, I get filthy and have a bad habbit of getting my greesy hand on just about everything.

the 350 crate engine thats in my pontiac firebird has hand prints on the cast aluminum parts. and I cant find anything that will get them clean. I have used hand cleaner, foaming engine degreaser, and it still looks like crap, so it has been about 1 1/2 years now. and I am afraid to take a picture of it with the way it looks.

what do you use on the blower to keep it polished?

and I dont like Wenol pollish. I think it's to ruff on polished aluminum. I used it once on a set of $3,500. wheels and it left fine scratches and just seemed to dull them.
