I searched but I'm not sure what exactly the name is for it, but I want to remove all that sound deadening mat in the back of the car. I have heard some people say dry ice is great to use to break up the material so you don't have to scrape forever. Anyone done this or have any good ideas on what else to use? I appreciate it.

 

Dry ice works well if you have access to this.

I have also heard that if you can locate several old CO2 fire extinguishers, they does the same thing- spray them on the sound deadening material and then hit with a hammer.

Here in the Great White North, the hot ticket is to sit the car outside overnight in the winter and then hit the material with a hammer- same effect as either of the above.

 

I used an air chisle.. worked great in 90 degree weather.

 

Another posibility is to get one of those bike tire enflaters that uses the BB gun CO2 cartriges. You'll need to buy quite a few though.....

 

you can buy dry ice from any ice cream vender place....look in your phone book.....dry ice works by far the best out of everything else.......when you get the dry ice ,place it in a bucket and crush it up into alot of little chunks then spead it across one area at a time..make it cover the entire area and let it sit for aproximatley 10 minutes,you will hear the sound deading start to crack then pull the dry ice off and it will peal up nice and easy.......

 

there's a ton of dry ice vendors within 5 miles of me. i may give it a shot today. thanks for the feedback guys.

one last q: what sort of gloves should I use? dude, that stuff is -109.3deg!! home depot has some thick rubber gloves but the guy there recommended leather gloves with insulation. any ideas??

 

I say just an air chisel. We did it at 3 in the mornin, about 65 deg. Neighbors weren't too happy though.
And Its fun!!

 

for the gloves... id either get some leather gloves, some old snowboarding/skiiing gloves, or anything really.. it doesnt really matter that much..

 

liquid nitrogen @ -365deg F??? Never done it before but that may work... hehe

 

I used a small propane torch and putty knives. Works, but takes a while and takes some elbow grease.

 

dry ice worked like a charm. damn, just a minute or so on each part of the material and it came up in sheets. thanks for the help everyone.

oh, part of the reason i did this was that i know a couple of dc2 guys who said it shaved around 40 lbs off the car's weight. maybe the rsx uses lighter material cuz at best from the hatch area only 5lbs would be a liberal guestimation. this stuff is pretty damn light. oh well, 5 lbs is 5lbs and maybe when i gut the car to do the rest it will be another 5-10lbs under the seats.
