Thanks for all the responses to my question. I've been educated! I don't think I'll scrape any off to have it analyzed, though.

Dick Aliminized steel is a type 1 aluminum-silicon alloy coated steel. Cold rollled steel is hot-dipped both sides with aluminun-silicon alloy by the continuous strip method. This process assures tight metallurgical bond between the steel and the aluminum coating. see www.precisionsteel.com/product.cfm?subsection Uses include wide variety of applications including mufflers and exhaust pipes.

As some of you know, I am in the process of a complete redo of the paint on my 35,000 Mi 67 Crown 4 DRHT. Since I am changing colors (OH! The Horror!) from White to Regal Blue, I have had to strip the complete car to a bare rolling shell, so that I can get at all the interior sheetmetal etc. I find that just about every metal surface, no matter how hidden by upholstery, parts etc. is painted or at least has overspray of the final finish color. I did find one exception, and that is the underside of the rear package shelf - that is completely bare metal. My car has never been out of Southern CA, so it has no rust anywhere, even on this bare metal. Inspecting it carefully, I think it might have an aluminized coating on it, as it is just a little too pristine for bare metal, even out here in the desert. Any suggestions as to how I can determine if this is indeed the case? I'm sure the coating is very thin, so the magnet won't be any help, and I don't want to scrape it. What do they mean by "Aluminized", anyway? Anybody know?
