Mike is absolutely right. Though the stuff is used for just this purpose
in new cars and therefore isn't going to produce rust or corrosion in
and of itself, if the box members being filled aren't properly prepared
first, you are going to have problems. I haven't seen the instruction
for these products, and they may give specific dos and don'ts But I
would think that all rust should be treated first with an agent such as
Rustmort or Ospho, which will convert the rust to a stable iron oxide
that is not reactive and will not corrode any further. Then a coating of
some sort might be in order, like a paint or something. As I say the
specific product may well have instructions as to how to use it in an
older car, once it is released for consumer use. Of course as it is used
now, during production of a new car, the situation is completely
different.
