Len Posted January 26, 2002 Share Posted January 26, 2002 I'm not sure but I was going to try using one of those cheap sandblasters from harbor freight. If you have interior stripped,may work. Then vacume it up after. But I haven't tried it. Just a thought. Len Quote Link to comment Share on other sites More sharing options...
jimzdat Posted January 26, 2002 Share Posted January 26, 2002 That stuff just laughs at sandblasters--tried both aluminum oxide and ground glass--best bet is just use paint scrapers/utty knives/screwdrivers/explosives/etc... I found that in many areas, once I got going large sections would come up easily--just had to work hard in some areas Quote Link to comment Share on other sites More sharing options...
zgeezer Posted January 26, 2002 Share Posted January 26, 2002 Freeze the tar and then use a wide chisel at an angle on the top and a hefty hammer. Large chunks will pop off leaving, as always small amounts to work on. How to freeze it? Up north park it outside for a week, ice sort of works, but is messy, Dry ice really works, but requires care, thick leather gloves, and a dry ice disposal plan other than tossing it into the garbage or flushing it down a toilet. Do not dispose of it by placing small amounts in 2 litre plastic coke bottle, adding 1 cup of H20, and screwing down the cap. This is irresponsible and creates extreme pressure that will within a minute or two rupture the plastic bottle and generally excite the neighbors, your dogs, and the local constabulary.

Wagz Posted January 26, 2002 Share Posted January 26, 2002 It came off easily and in large chunks from my 240. All I used was an old 1" chisel and rubber mallet to bust it loose. Wasn't too much work at all. Quote Link to comment Share on other sites More sharing options...
johnc Posted January 27, 2002 Share Posted January 27, 2002 I used the dry ice method mentioned above. Layer it on the floor pan for a few minutes then bash away with a rubber mallet. The asphalt stuff all broke off nice and clean like peanut brittle. I ended up throwing the leftover dry ice and and asphalt into the trash. Don't know what the concern is about that method of disposal. Quote Link to comment Share on other sites More sharing options...

It's great fun to put it into containers like soda bottles partially filled with water where it will explode (oh, did I say that?) I guess flushing it down a toilet can be a bad thing if it ends up in a septic tank or something--wouldn't want to 'burp' that puppy, no way no how.

Guest ShelbyZ Posted January 27, 2002 Share Posted January 27, 2002 The best luck I had getting the stuff out of my 69 240 was waiting until it was about 10 degrees out or colder. I got the chisels out and went to work. I tried it when it was warm out and it seemed as though I was just moving it around. When it was cold it did sometimes come off in small sheets. Especially on the tranny tunnel. I saw why the floor rust on these cars. They put the dynamat on and then painted the car. I finally got it all off, but I really detest that stuff. Needless to say I didn't put it back in the car! Good Luck! Keep ZZZZZZZin ShelbyZ Quote Link to comment Share on other sites More sharing options...
Guest 400 ci 280z Posted January 27, 2002 Share Posted January 27, 2002 what is the best way to remove those tar mats in the interior. is it dry ice or paint stripper? Quote Link to comment Share on other sites More sharing options...
Dp351zcar Posted January 27, 2002 Share Posted January 27, 2002 what I tried was to use a blowtorch to get a thick puttyknife hot and it seemed to cut through pretty good, until the knife got cool. Don't know of any tool that has a hot blade but if there is it should work. I think that there is not just one way to get it all off, it will take a combination of ways to get it off one car.

Jeff Posted January 28, 2002 Share Posted January 28, 2002 Eastwood sells heavy duty scrappers and these worked well for me. Took me about 6 hours and one blister to get it all out. Some of it came out in big chunks, but most of it was small pieces. Quote Link to comment Share on other sites More sharing options...
Guest 400 ci 280z Posted January 28, 2002 Share Posted January 28, 2002 it took me about an hour and a half to do the passenger side and clean all that crap up. there is still a little caulking left but a little more scraping should take care of it. i am going to start on the drivers side tommorrow.

Guest gprix1 Posted January 31, 2002 Share Posted January 31, 2002 Can anyone suggest where to buy dry ice? I've never seen it for sale anywhere. Quote Link to comment Share on other sites More sharing options...
johnc Posted January 31, 2002 Share Posted January 31, 2002 I got mine from Chino Ice Company down here in SoCal. Look in your local phone book for ice or specialty gas companies. You can also check http://www.dryice.com. Quote Link to comment Share on other sites More sharing options...
Guest 400 ci 280z Posted February 1, 2002 Share Posted February 1, 2002 at the wal-mart here they sell it by the customer service desk. Quote Link to comment Share on other sites More sharing options...
Guest 2adz Posted February 1, 2002 Share Posted February 1, 2002 I used a propane torch and a scraper. I kept the heat on the undercoating just in front of the knife and it came off like a knife through butter. Now my Z was completely disassembled and on a rotissery so there was no risk of fire due to gas fumes, so keep that in mind if you go this way.
