I just found out I have an inside track on buying dynamat at cost through a vendor I do business with. Question is, has anyone used it and report some results? I read the thread about using the Hardware flashing that appears to be close to the same stuff, but wanted some feedback on Dynamat specifically.

My plans would be to put it under the carpet and as high up the firewall as possible, inside the doors behind the speakers & window hardware, and behind the carpet up the sidewall where the jump seats are up to the window and across the back wall of the ext. cab part.

I just want to make sure this stuff will quieten down the truck, as that is my biggest complaint.

It does a tremendous job. I have used it for years on stereo vehicles. I would advise you to use the dynamat extreme. I have seen the original stuf end up in a puddle at the bottom when mounted on verticle surfases.

It adds a layer of insulation to the vehicle, but it also stops the metal from vibrating so much. That is the big plus in older vehicles. I normally use it in strips about 3 inches wide. You can do full cover, but it can get expensive. I buy it wholesale also. I see the kit I pay 114.oo, in the stores for 200+. The speaker kits(useless unless you only need a half a square foot) cost me 6 bucks and sell for 20+

BTW.... Use a roller when installing it. It does make a difference.
