HiFlow5 0's headlight sanding tip is good and it works. Eastwood makes many polishing compounds for metals and plastic. I have used these with a buffing wheel on a hand drill and the results are well worth the effort. If you have a set of aluminum wheels, like a older set of Welds that have gotten a nasty look, you can do a sand and polish job on those as well. It's better if the tire is off the wheel but a good polish job can still be had with the tire mounted. You can do a final sand with 600 grit on the aluminum. If 600 isn't enough to get the metal clean, use a grit that is just aggressive enough to get the job done. It's better to use some dish soap in a bucket of water and wet sand the wheels versus dry sanding. Keep a towel handy for wiping the wheel to keep track of progress. If you had to use a rougher grit, you will have to work your way up to the 600 in steps to remove the scratches left from the previous grit. Your're done sanding when the surface has a soft, smooth satin like finish and feel. Then, one of Eastwood's aluminum/brass buffing kits will help you do the actual buffing. This is a 2 step process because of the 2 different grade compounds needed. They have instructions on that, so I won't go into it. After you do the machine buffing, all that is left is to apply your prefered cream polish by hand. This is a labor intensive job but you can have better than new looks for alot less money. Be forewarned, you will also lose your finger prints for awhile from all the sanding.
