I was looking at a sprite that had expanding foam put in all the
cavities. It was at a fabricator's shop for repair. He had it dipped
in a hot tank then in a phosphoric acid tank to get it all back to
clean metal. Unfortunately the foam didn't budge in either, but
the results of its use were very visible. Severe rust rot everywhere
the foam had been used. The car is a disaster.
Apparently it was in pretty good condition when the owner used
the foam for "protection and stiffening". He is now paying a high
price!
They now have to (tediously) remove all the foam by hand as they
have had no luck with any automatic technique like water or sand
blasting either. The only thing that seems to work are really nasty
solvents.
So, please - *DONT DO IT*!!!

Enrique,
This material also sticks to skin, clothes, hair...EVERYTHING!! There are
different types, some expand more than others (check the can for the
volume). Also, don't use it on your car, if that's what you had in mind.
I know folks who have done so, to kill road noise, and found themselves
with rust problems where it usually doesn't occur - this stuff retains
moisture. And best of all the stuff expands with great force and can
warp and disfigure - fill a beer can with it, drink the beer first, and
see what happens.
Mike
