I would certainly agree with Chris. I would recommend against spray on
undercoatings.

Kool Patch is not a spray. It is actually an asphalt/fiberglass emulsion
that spreads on with a coarse bristle brush, like pudding. It never fully
"dries" but forms a thick, leathery semi-solid, kinda like roofing tar. Due
to the glass fiber strands, it doesn't crack, at least our hasn't and it is
3 years old.

I think Kool Seal warrantees it for 8 years when used as a roofing patch.
Durable stuff.

thick layers of tarry spray on undercoating can actually lead to rust, by
trapping water underneath the undercoating, where it never dries out. if
you
must use some sort of spray on undercoating, i'd reccomend the parrifin
waxy
style undercoatings, which seep into cracks better, and are sprayed on at a
high temp, so they are very liquid, then dry.  the less coats, the better.
the more thick the undercoating is, the more the likelyhood it will
seperate
from the body, leaving pockets behind that trap moisture/dirt.
