polishing aluminum?

[litew8]

I polished my outter grille! , and, I used the yellow heavy duty stuff.

Let sit 10-15 min then rinsed. Not ALL of the anodize coating will lift free, sanding needed. I had lots of scratches etc... Check my build thread for pics. Some info is wrong about sand paper used (mistyped the order of grit used). I still need to clear coat (in can) it to protect. Turned out sweet! (IMHO), took a long time but well worth it to me.
