hey guys how do i take sound deadening of rear floor to polish it and make it look all pretty?:please:
 
Bags of ice, get it cold then chizzel it off. Do not heat it up, will make a right mess!
 
Depends how hard it is. We just chiseled the sound deadening out of my brothers Daihatsu GTTI without ice. Came off in big chunks using a big flat screw driver and a hammer.

Give it a bash and see if it works. If not use the ice or dry ice if you can.
 
Dry ice is the easiest way to remove sound deadening. Set a block of it on the deadening and wait a couple minutes, the extreme temperature change will break the bond between the metal and deadening. That's how i do it, takes the least amount of time and dry ice is relatively inexpensive.
 
ok well i shall need to try this tomorrow, will it scratch the paint as i want it to be shiney n shiz
 
Where the hell would you go to buy dry ice?

Well it all depends on geographical location, the best way to locate a dry ice distributor is searching your local listings or online. Otherwise if you know of a meat packaging facility, or see someone vending ice cream on the street via cart, you can ask them. I'm personally lucky to be 40 minutes away from a dry ice distributor, so i can get which ever form of dry ice i want. Usually you'll most commonly come across the little bricks roughly 4"x8"x2" in size. Otherwise if you're lucky like i am, you can find it in a pellet form, basically looks like a snowball that is easily spread over surface area.

If you decide to go this route a couple safety tips to keep in mind. First while transporting it, make sure you have a decent cooler to store it in for transport, and also ensure that your windows are cracked to allow air into the car. This is compressed CO2 in a solid state. Also be sure to where well insulated gloves since it's temperature is -78.5C. You can find more safety tips online when it comes to safe handling of it.

It is by far the fastest way to accomplish sound deadening removal that i know of.

I wouldn't worry about dry ice, years ago I used liquid nitrogen to remove the sound deadening from my EF8. By far the most easiest way to remove it.

I will dig out the video and post it on YouTube! I'm not going to say where I obtained it from but one thing to remember is that it can't be kept in a sealed container. We decanted some into a thermos flask and gently rested the lid atop (so it could vent). When I got to my garage we poured it onto the sound deadening, waited a few seconds until it had evaporated and then hit it with a rubber mallet. Sound deadening broke off like chunks of biscuit. No damage to floor pan and relatively mess free.

The only thing I will say is that you will be surprised how many industries use this stuff and if you look hard enough you should be able to find a decent source.
 
me and the other keith (D17 KDB) done ours, car shell was pretty cold, used a hammer and it all broke up into bits! SIMPLES!!!

If you do get some sticky stuff, just use a screw driver and a hammer to get under it! Most likely going to be primer under the stuff anyway as most peoples were put on between primer and paint, luckily, mines was after paint so its nice and clean :p

If you are unlucky with primer, will have to be painted anyway! So scratching it wont be a problem.

Rough weight saving was 10kg including under the front seats! :nice:
 
i´ve been trying some oil bath and works really good !! put some engine oil (old one)and let it stay for a couple a days , it will be quite easy to take the sound deadening out after that...
 
heat gun seems to work well for me, then use petrol on a rag to get the resadue off :)
