DynaMat on interior of roof
 

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

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
