I saw a bunch of posts about how to remove it, but nothing that someone actually tried. So whats the best way to get it off the trunk floor, heat gun? dry ice? chisel? what?

Why are you removing the dynamat?

if you cant cover the dynamat area with carpet ie the trunk lid then carpet the trunk lid.

I've only removed small pieces, like a foot square, but what worked for me was to cut a slit in the mat and then work a small putty knife under it to get under an area about 1" wide x 1/2" deep. Then grab the piece with some heavy duty pliers and pull like hell.

I think you will be better off trying to break the adhesive bond than doing anything that would soften the damping layer, which will probably give you some mat in your hand and some on the car. I think heat would cause the softened mat to divide internally instead of at the adhesive layer. If you can get a piece moving, you might be able to speed up the bond breaking with acetone or something.

Like I said, only done small pieces. Email Rick at RAAMaudio for a definitive answer. I know he has done this many times and is usually happy to answer this sort of question.

i don't have subs anymore and don't want the extra weight back there. So I'll try small pieces at a time, but its very sticky since I installed it so well. I try to pull and nothing moves, usually just the aluminum part rips off and leaves the tar behind.

The extra weight isn't worth the time to remove it. There's gonna be maybe 20 lbs, not enough to make a noticable difference in your 1/4 mile times, or auto-x, etc. I say leave it in there, and don;t worry about it. Regardless, if you insist on moving it, I;ve done it several ways. Chisel (air chisel if you can get one) works, putty knife works fine, dry icing only makes it hard and britle, and chips it into fine pieces. The heat gun/putty knife combo is fine, but you kind of get a gummy mess.

20lbs adds up. I removed interior carpet and floor mats, thats another 20lbs. I don't care what it looks like cause its under the main floor where my amp is. Thanks looks like i'll be gettin a chisel.

yeah, i used air chisel when I worked in a body shop. First you trim the big piece of first then use some wax and grease remover or what body shop called "500" to melt the rest of the dynamat around. Once you put 500 on the dynamat then they will turn into liquid. This may take a couple of hours or more to do it.

man this sucks, i got maybe 1/2 out but its rough and my hand is all cut from the metal Well i had an accident and the 1/4 that the body shop had to fix was easy cause the mat just pulled off and there's water and rust underneath. I hope it isn't a bad leak. I might just give up on the rest cause its a very slow process of scraping. I'll get some carpet and just cover over it on the bottom so sticky stuff doesn't get everywhere.

removing dynamat to save 20lb=real enthusiast

 
Rep Power: 812

haha thanks every bit matters. I already took out the heavy carpet and mats and just put some cheap stuff on for looks. And keeping the washer fluid low saved another 5-8 lbs!

Just get a heat gun or hair dryer, heat it up, and it should come right off

All that time and money you invested in putting the dynamat just to get rid of a few pounds..Dunno man that seems a bit extreme to me.

 
Rep Power: 812

well i had subs back then, now i dont. no need for weight when i'm tryin to make the car faster...

try using gasoline. when i worked sheet metal roofing, we would use gasoline to get the nastiest roofing tar off of our equipment.

Take out the carpets and get that ish some rhyno liner! You know that spray on truck bed liner they say you can use anywhere.

perhaps offer to trade your trunk for someone else's non dynamat'd trunk


oh try takin a big **** before you drive too, that should free up a bit of weight

 
Rep Power: 812

lol guys the lid is fine. its just the trunk floor i wanna get most out. Its covered with the floordoard anyway but i might put carpet under there later. Its just going really slow.

I sincerely hope you're kidding.

good luck trying to remove, I removed mines but tar still stays. Its on the trunk now so I just left it like that til I get a carbon fiber trunk.

 
Rep Power: 329

That's because it's a civic, not because you have 20 pounds of tar in the trunk.

 
Rep Power: 300

To remove the residue you can use this stuff called "bug and tar remover" it takes off what you cant peel easily. Well at least it worked really well to help remove my edead and make it look like it was never there.

Found an answer that might help. In the course of testing a series of different brand damping mats one thing disolves them all - turpentine. If it is Dynamat Original or another asphalt based mat, it will literally turn it to liquid. If it is Xtreme or another Butyl based mat, it will turn it into something the consistency of axle grease. You should be able to pull out all of the aluminum layer and then easily scrape up the goo with a putty knife. Wipe down with turps on rags and you should be at clean metal.

Gonna be a big stinky mess, but safer than gasoline and no muscle power required.
