Sometimes I'll use a wire wheel to clean it up. Pretty quick way to get all the grime off and make way for some smoother polishing.

Use 220 dry to get out all of the casting marks/imperfections.
400 wet to get out the scratches from the 220.
600 wet to get out the scratches from the 400. The piece should have a low luster at this point.

Go to Lowe's and get the polishing compound in the plastic tubes. I would recommend 1,2, &4. You need a different yellow (hard) wheel for each of the #1 & #2 compounds. Don't mix wheels. White (soft) wheel for the last compound.

Prepare to spend 40 hours or more on a perfect piece. Do it right and it will look similar to below.

I'd love to clean up inside my engine bay, but that's almost TOO shiny.

40 hours! Now I'm demotivated to even try lol.

I wanna do my intake pipes and manifold and alternator and tstat housing. shouldn't a drill with the sand paper mounted make it shorter?

In that case just 1/2 *** the sanding up to 600 grit and use some Mothers Mag and Aluminum polish.

An alternative you might want to try is glass beads under lower air pressure it produces a satin type of finish looks nice and clean , we do a lot of motorcycle heads and so on that way .

The intake you could clear coat after I don't think there is enough heat to bother . just make sure you mask off all gasket surfaces and blow the hell out of it with air to make sure all the beads are out before installing . The thermo housing would be simple to do . The only real down side is the beads get in EVERYTHING and parts need to be cleaned thoroughly before installation . The alternator would need to be totally disassembled including replacing bearings .. IMO polishing looks great for a while but soon begins to tarnish again just from air exposure if nothing else .

It's a lot of work but the end result is super .

thanks for that, sounds like more work then i thought

what if i just did a certain amount of sanding, not to get a shine, but enough to put on a nice paint job, so that i dont have to worry about the shinyness anymore

since it does go away quickly, and you can just repaint if the paint gets old

is that all safe to assume?
