I'm a Streetrodder, there is a lot I mean a lot of billet aluminum on a custom, wheels, valve covers, Streering wheel, door handles, cranks, engine parts, pumps, on and on and on. I simply took a micro finer polishing cloth a can of Meguiars Hot Rims and a few minutes buffing and I had a mirror finish. Simple. I also use Chrome Polish on my PVs including the black chrome and the gold. The only exception I ,made was to my MVP which I purchased a wrap for called Black Mamba, wicked cool, I ask the vendor for a little extra and wrapped a couple of ViVis to match, makes a very handsome rig. Really a beautiful job removing that knurling, very well done. Mine came that way so the polish was enough. I also spent a few minutes in a hardware store and bought all new metric hardware screws,nuts washers all anodized black and put a number 2 hex wrench and a sharp pin ( made from born trussing pins ) and a very small phillps on a ring I carry as tools. Now, if I could only roll a constant wick and coil I'd be happy.
