I know Dynamat is heavy..... I've only sprayed Lizard skin heat/sound control on the floor/trunk of my Chevelle so far.

Any lighter options for the roof? I have to do mine still and it looks to be a very messy job.

In the building of my '40 Ford Pickup --- one of the things I want to really address is the A/C.... having had many hot rods over a long period of time -- The A/C in these has NEVER been worth a darn compared to the A/C in a new automobile.

I like to drive my hot rods -- and I'm looking forward to driving this '40 on the Hall of Fame tour etc - which ends in Texas. I live in Idaho and it's warm but not hot in the summer... but we have plans to move to Scottsdale where it is darn hot!

With that in mind -- we're going to install Restomod Air Membrane in the truck. This is supposedly a dual purpose THERMAL barrier and sound deadener....

Glad to see this, trying to get the stuff together for my TMI headliner swap. I currently don’t have any insulation with the factory style headliner and my vintage air blows cold air but with the Florida sun it is still “warm”. Not hot but doesn’t come like in new car. I understand that my car is not as built as well as a newer one but every little bit helps!

wurth sells nice 10x22 sheets of sound deadening panels that are heavy duty bitumen based material with a polypropylen covering. seen it on oem roof panels of benz or audi etc. Stuff is real nice quality and i think it has more
stiffening properties than dynamat. In some cases of ex vinyl roof cars that were weakened by pitting or corrosion that stuff would really help.
Used it on both of my builds very happy with that product.

here is sample link, though i ordred direct from wurth rep.
