This stuff sticks quite well to bare and painted metal surfaces.
Years ago I pulled the carpet and laid down this stuff. It isn't actually the "Dynamat" brand, this was called "Rattle Trap".

Now I need to do some transmission tunnel work and this stuff needs to come up.
I imagine that colder weather may help with removal since the soft backing won't be as gooey as it would be in the Summer.
Are there any tips to removing this stuff? What about the black stuff that may remain after removing the foil? Alcohol? Acetone? Lacquer thinner?
 
Step one, figure out how far out you need to go and use an exactoknife and cut the area to be removed.

Step two.. good luck fella ! :thumbsup:
 
I have an impressive collection of chisels and scrapers....
 
The solvent used will depend on whether the stuff is asphalt based or butyl.

Figure that out and search how to remove.
 
i like the heat idea why not use a heat gun under car as said then as you start to remove spray wd-40 under it will help to remove .
 
My thoughts are that heat makes it stick better and that the colder the stuff is, the harder and less sticky it might be.
 
You need solvent and a lot of scraping.

Just cut the area with a razor knife/box cutter and squirt solvent in the cuts. Let it work and then scrape, peel, squirt repeat. Is your mat butyl based or asphalt based?
 
Well it's good to see you working on the old rattle trap anyway...
 
Did yah read the link I gave you Greg! It suggests warmth.. not a lot of heat and it will peel !
 
I have bad news for you, Kern. From Rattletrap product info:
Rattle Trap Super Stick is unlike any other sound deadening mats available and has a patented super seal formula that sticks to virtually anything! Not only will it stick, it will stay there once installed for the life of your car.
 
I have the same stuff in the Coronet. I don't ever want to deal with tearing it up.
 
I've seen people use rubbing alcohol and dry ice to freeze factory sound deadener, not sure if it would work for asphalt but probably would be enough to get a knife between the deadener and metal and hopefully break it off in chunks.
