Rustproofing on boxcars (Was: '67 or '68 promo model)?

["Dick Benjamin" <DickB@xxxxxxxxx>]

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?
