DynaMat on interior of roof

[AB69Z]

Ok so I'm ready to install the DynaMat Extreme to the interior of my roof and of course I hear that I shouldn't do it. I see it used quite frequently, so has anyone had or know of any potential issues with it installed in that location.

The sun heats up the dynamat and it will start to lose it's stickityosity....... I've also experienced this when doing the inside of the actual door skin.... versus just the inside covered by the door panel.


I think it's may be a matter of how CLEAN the steel is.... but I'm not certain.

I lined Dynamat the entire underside of the roof of my 67 Firebird. I've parked the car outside under the hot Texas sun with no issues. I think surface prep is the key. I cleaned the metal really well, plus I sprayed the surface with 3M adhesive before applying the Dynamat.

X2 no issues when applied to clean surface.

I had the entire inside of the roof POR'd and I have to admit I was still worried that in the hot Fla sun the dynamat would eventually release and cause issues so I decided to go with some DEI insulation between the roof and the headliner. Only time will tell. I do agree that prep is the key :yes:
Good luck

stickityosity.......

I like that word Greg...

I lined my roof and door skins about 6 years ago with no issues. Just make sure the the surface is clean and roll out on good and you'll be fine.

I used dynamat extreme on the roof panel of my second gen back in 2004 and have had zero issues.

Me too...since 04, but mine only sees constant sunshine when we actually have some. This stuff is a bear to remove when heated well. I'd do the roof again for sure.

I did the entire interior with Focal Bamm including the roof. As said above, clean surface and careful installation= no issues

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.
