But depending what kind of manifold it is, it can get costly. I've layed out almost $400 to get a tunnel ram polished, but there was no way I could make it shine like they did.

Now, if it has never been polished before I'd recommend just taking it to the guys that do it all the time. The work/time to get it from a raw casting to polished is crazy.

in that case, either pick up some jewelers rouge and go at it or just the mequiars and get busy

You could try wet sanding it With 2500 and 3000 grit paper then the mothers.

Do you have a bench Grinder?

heres what my scoop looks like after wetsanding 400 -> 600 -> 800 -> 1000 -> 1500 -> 2000 -> 2500 then buffing with a bench grinder and white rouge, then green rouge, then finalizing with Mequiars polish

it was already polished, but very tarnished from sitting around for years in someones attic.
