anyone have any experience with or have you heard anything about the spray sound deadeners?

Seems like they would be easier to install, and they appear to be cheaper than the normal dynamat stuff.

I know RF came out with some in a can a while back and i just happened ot see this company on sounddomain - cascade sells stuff in buckets.
 
I used once and it sucked you need to layer the hell out of it to get a result.
 
I used to use the pray all the time and loved it, but in can form you just will have to spend too much money. For a door you usually need 2-2.5 cans and trunks need 5-6 cans, it can add up fast. I always kept 2 10L contianers or Dynashield spray in the shop with a sprayer hooked to the compressor for full body spray work. that's when it becomes really useful as you can get all over deadening with minimum weight gain. Even at that a single car will on average take 2/3 - 3/4 of a container. For smaller specific areas you are better off staying with the sheets and laying that, as the spray also requires very careful masking to prevent over spray on sections you don't want covered.
 
I used the Dynamat Extreme and dont think I would bother trying anything else. It kicks so much ass. Don't be stingy with it.
