Yes, I have used it on many polished aluminum parts but I use it as a protectant, not as the primary polish. It leaves a clear silicone film to protect against dirt, grease, brake dust etc. Dirt, brake dust, etc just wipes off. The protection lastes about 6 months. It also has pretty good protection against oxidation & pitting.
Again...I use a high quality aluminum polish first, then coat with Rejex.

I'm like Eddie...use it as a protectorante and like it. Especially just before a road trip...makes it an easy clean up upon arrival or afterward. Going to Florida, slicing through the air at top speeds picks up a lot of bugs. With Reject...they wipe away.
I also use it when I remove my C5 wheels for a thorough cleaning on the inside where my hand can't reach. It keeps it relatively slick so brake dust and road debris doesn't collect...seems to make it easier for quick touch up cleaning.
