Yep. That's what got me interested in the stuff.

I'd still like to hear from someone who has used _this exact product_,
and how things turned out for them.

I've gotten a few comments from people who are obviously speaking in
generalities, and making invalid assumptions. One called it "tar shit."
It isn't, it's a bitumen (asphalt) emulsion, and asphalt is the
traditional undercoating for cars. As a matter of fact, 3M Body Schutz,
a well regarded undercoating, is asphalt based (but 8X the price and
only recommended for spray application). Another referred to something
"gold-silver colored" (Kool Seal is black).

VW used some sort of undercoating material during manufacture, then
painted over the top. Anyone _know_ what that was?
