Does anyone have experience with Dynamat products. My car is in the paint shop and the interior will be taken out. I have the opportunity to add some thing and am looking at this type of product.
Thanks,
Jason

Quite a few fellers here have used it, and I think everyone has been pleased with the results. I haven't tried it myself....yet.

Jason, if you do a search here for "dynamat", you'll find several threads on different types of insulation, and member's opinions/experiences with them. I'm surprised no-one else has chimed in on it...

Dynamat is heavy and expensive. I did the interior of my '73, and then covered that with Dynapad to block the heat. Be aware of adding too much thickness in areas that might prevent re-assembly of things like the console.
let us know how it turns out,

I used stuff from Lowes, it's about 1/8" thick silver foil over a foam I think. Can't remember the name. It's in the insulation department, comes in rolls. It form fits very easily and works great.
I used the aluminum tape (for duct work) to seal the seams. Just a thought.

Used it when putting "BIGBRRD" back together. As mentioned above I just made sure to trim it back a little where there would be some fitment issues. It has helped to quiet the interior down some and reduce the heat from the exhaust system.

Dave, I believe that the foil faced foam is for heat only. The Dynamat has to go down first and be firmly attached to the panel, then the Dynapad or Reflectics (foil faced foam) goes on top of that.

I used Dynamat from front to rear. It quieted down road noise a noticeable amount and really cut down on the heat when I had the full exhaust w/cats. My wife did notice that the heat was cut down considerably. Her legs and feet didn't cook like they used to. Along with my tinted windows and shades for the glass t-tops the A/C worked a lot better.
It is heavy and expensive, but that wasn't about to sway my decision from using it. I figure I already had and still have stupid amounts of money in a car that I will never recoup. But I never built this car to be an investment.

I wasn't concerned with noise, just heat, but it did help a bit with the noise.
