<< 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. >>

no offense - but that's exactly the stuff i WOULDNT use..   you dont want to
cake up some thick tar undercoating spread on with a putty knife......you
WANT it to be thin.  the thicker and heavier it is, the more of the chance it
will sag - and seperate from the underlaying metal, and leave pockets for
moisture, dirt.
here's a case history...
my dad has a '80 dodge van. a long time ago, (around '86 when i was in high
school) i thought it would be a "really good idea" to smear roofing tar, and
spray on foaming crack filler around all the seams, and sheetmetal on the
inner rockers, and inside the rear wheelwells, under the van, to "protect it
against the salt"
now the van is full of holes.
more so, than if i had just left it alone.   all that roofing tar crap is
smeared on there, held water, salt, and dirt behind it, and rotted it out
from behind. all it takes is one little pinhole - to start to let water
behind that caked on tar and it will start to seperate from the body..
A year ago, i got under there, and pulled off some of the BIG HUNKS of
roofing tar that i put on there 10 yrs ago, and they just fell right off, in
my hands - i didnt even have to scrape it off - loaded with dirt, and rust
holes behind them.

roofing cement is for roofs...  BTDT, and was really sorry...
