Anyone ever used the brush on/spray on sound deadener.

Okay, so this is not quite a Camaro subject.  But it is for my 69 project.  Has anyone used these spray on sound deadener to quiet the car.  The claim seems to be quite high.  Does this stuff actually work?  Or is it a waste of money?

Here is a link to the website selling the quiet sound stuff.

Well, this is a non-Camaro answer.  Last year an AACA buddy of mine did a whole lot of work on his Corvair.  One of the things he did was to add sound deadener.  The kind he used was more brush on (and nasty to apply) than what appears on the website you listed.  I can only tell a very slight difference (and in a Corvair... well, who cares?).  But he swears it is a noteable diiference.  So, I pressed him and he says, "Well, maybe about 25% quieter..."
