[s-cars] another list lurker finally buys an urS4! andaQuestion...

[Kirby Smith]

There was a suitable product, no longer available as far as I know;
killed off by high cromium prices during the '70s.  It reacted with the
rust to form a very hard, and difficult to get re-rusting coating. 
Permatex has an acrylic product with something functionally similar in
it, but it doesn't work well for painting car bodies.  I haven't seen
the bare chemical since the '70's.
