Hello all. About two years ago I had Tweeter (f***ing idiots) install dynamat on my door panels, and around in my trunk.

Well, my driver-side window motor needs to get cleaned/replaced. I open up the door and realize that the dynamat black tar & metalic paper is covering up the nuts/screws that hold the door panel together, and also covering the "seam" where the metal panel of the door comes off and provides access to the window & motor.

How can I get around this? How can I "cut" through this black tar stuff so I can get my door apart?

 

did you try a razor blade?

 

not yet. I wanted to get people's feedback before I started butchering this. if a razor is the only way to go, so be it.

 

get an xacto knife that you don't care about, because its pretty hard to clean after you get all the goop on there and start cutting pieces out and then try prying them up with the knife... also might try freezing it with ice packs? i know that when i was installing it in the heat, it got REALLY sticky

 

i don't know if this applies to dynamat, but people use dry ice to chisel the OEM sound deadening off of cars, which is probably similar material. YMMV

 

yeah that's what i was going for with the icepacks.. but dry ice is probably the only thing that would work, just harder to get your hands on

 

Did this before when I was working with temporary baffles in my previous car. I used a box cutter. A razor or xacto knife will work just fine. To remove the goo, use goo gone.

 

k thx. Going to get a box cutter with a really good grip and a ton of extra blades.

 

Box cutter for the record. Heat up the dynomat with a blowdryer so the tar underneath loosens up.

 

god that must of been a pain in the ***. im starting to install dynomat but im being really careful where i put it.
