nc_mystic I'm not familiar with that particular product, but I can tell you that if you go to just about any big car event you will see at least one or two stands showing off what they claim to be the "ultimate" polishing product. Like so many products out their they will wow you with their display and make all kinds of claims... imo they all work about the same, their is a small amount of "grit" in the product that will polish aluminum. Granted some are better than others for different applications. It doesn't hurt to try a couple different kinds.
I'm a fan of mother's billet polish, you can pick it up at any autozone, advancedauto, etc.
Just logged on to svtp, it looks like somebody has done a review on the shineseal stuff, you might check that out. I might take a look at it if I get time. Time for bed right now though.
