I can testify that the fixit stuff works great as long as the scratch is no deeper than the clear coat. Heck, even if it's as deep as the metal it will at least seal it up (it's UV activated so park it in the direct sun before you wash it off). I think the brushed aluminum even has clear coat sprayed on some of the parts so watch out and check it before taking the wire brush to it. I have an '08 and the clear coat used for the wheels is junk, my next mod will be to have the wheels blasted and powder coated.
