I always like replying to threads I started 4 months later. :)

I am so impressed with this. Installed the dynamat rather painlessly. My local audio store didn't have the wooden roller so I used a can.
Anyone who needs to cut the noise levels on there inline fan....This works awesome!!!

Thanks for this thread bro! I have done this to my fans and to my portable AC compressor, and it has dropped the sound in the room a few db's. Good Shit!
I'm glad this worked for ya guys. I was pretty suprised at the efficy of this mod myself and I've been sealing cars with the stuff for years.

A more effective, cheaper alternative to dynamat..
http://www.b-quiet.com/
Many of their products have worked amazingly for me...and saved money
I would avoid b-quiet - they aren't pure viscoelastic deadener, (butyl rubber) - they are a rubber-asphalt mix - which is why the stuff is cheaper.
It doesn't absorb sound so much as it massloads the substrate - makes the metal a bit heavier and thus less prone to vibration - whereas superior products made of pure butyl rubber like Dynamat Extreme or Damplifier Pro which actually absorbs the sound waves and nullifies them within the material.
There are alot of copymats out there - the cheap ones are cheap for a reason - but not because Dynamat is somehow overpriced.
Any pure butyl-rubber deadener is going to cost about the same as dynamat, sq/ft by sq/ft.
It also tends to shit out at a MUCH lower temp - maybe not so important in the grow room where even a totally fucked grow isn't going to get hotter than 100 or so, but fuck important when your car is baking in a parking lot in the middle of the summer for 5 hours.
You want that 300-400 degree heat tolerance for your doors and trunk less you get a real mess on your hands. Asphalt based deadeners just won't cut the mustard.
Dynamat Extreme or Damplifier Pro. I wouldn't fuck with anything else.
