Isnt the original metal with a thin coat of vinyl or something...? mine is quite faded , since its a convertible...I also use Armorall sometimes ,but it goes away...I`d like to get a clear coat also, but maybe with a slight brown in it to darken it up some...esp. since the cover for the 67 ashtray at the back was missing and I got a very nice one from FirebirdBill a few years back, so you see what it is supposed to look like
