Raw aluminum looks awesome, but it never stays that way. We like to shoot the aluminum parts with Eastwood's Ceramic Engine Paint... it is really nice stuff. We personally tested a piece painted with it to over 550 degrees with no change of color or sheen. Here, you see the LSA from "Lou's Change" has been shot with the silver to appear like aluminum in color, but it won't oxidize. The supercharger hat has been powdercoated in wrinkle black, and the DSE subframe is bathed in satin black Imron over epoxy.
