just like any other polishing... sand sand sand polish.

Start with a 120,220 depends on out smooth already and move slowly up to 600. At 600 start wetsanding and move to the highest grit you want.

If you have the smooth ones, I would NOT start with 120. You would just make yourself more work doing that. I would start with no less than 320, possibly 400. Then work your way up to at least 1000, then polish it.
The Eastwood Company has some nice polishing kit. Im almost done polishing my plenum/SLP runners/fuel rails etc. with a kit from them, and it has worked out nicely. Just a hell of a lot of work with the raw cast of the SLP's..!!
