Does anyone know where to get spray-on soundproofing and what brands are out there??

 

Cascade Audio makes a waterproof sprayable sound deadener called Vblok. I'm pretty sure www.sounddomain.com carries it.

Dynamat also makes Dynashield, another spray on goodie.

Rockford fosgate also makes a spray, and i'm pretty sure (but not positive) that Lightning audio has one as well.... i've only personally used the Dynashield, and it worked awesome for getting in the little spaces. Although don't spray too thick, or it runs and drips and it's messy and bleh! Good luck!!

Take care,
Tim

 

You can also use spray on undercoating. You can get it from pretty much anywhere. Pep boys, K-mart etc for about $4 a can. There are a couple of different kinds. But I think they are better then Rockford's or Cascade's because the undercoating seems to be a little tougher. Sprays on easy and is hard to get off so make sure you don't spray what you don't want to spray!!
