I'm already seeing this on the Tornado Red '86 5KCSTQ I recently purchased.
This car had been garaged throughout its life until the head gasket blew,
and I can already see the effects of oxidation from it having been outside
for the past two and a half months.  Needless to say, I'm going to cover it
and when I do the engine swap I also want to protect the paint as best I
can, because it's pristine except for a few chips on the front spoiler.  I'm
not seeing any adhesion problems, just a barely-detectible oxidation film
that I want to do my best to prevent getting worse.

Cheers,
Alex
'87 5KCSTQ, '86 5KCSTQ (red, almost perfect paint, but oxidizing without
proper treatment.)
