Hello Lindel,
I have heard that 79 bumpers were aluminum / chrome plated, but no where can I find that aluminum is compatible with chrome.
My 80 had a chromed bumper, which delaminated as you described, but it would hold a magnet. My new re chromed bumper also holds a magnet.
The bumper did not rust, just came apart in layers, I feel it is some sort of exotic metal mix, but still had a lot of iron in it, or a magnet would not stick.
I know that it means nothing, but I really would like to know...
