G Gress Posted November 3, 2003 Share Posted November 3, 2003 I've tried a search with no results. I'm thinking dry ice blasting may be the way to go to remove undercoating, rust and paint in the nooks and crannies. Sand/soda blasting seems to just smear rubber around. Talked to the ice guys today, but they had never tried blasting undercoating but did say it worked well on sticky glues and adhesives. Anyone tried it yet?

Guest Anonymous Posted November 3, 2003 Share Posted November 3, 2003 Never heard of it but When I removed my undercoating, it was about 30 degrees in the garage. The stuff came off real easy when it was frozen. Quote Link to comment Share on other sites More sharing options...
JKDGabe Posted November 3, 2003 Share Posted November 3, 2003 I don't know how it will work for you... I am interested in hearing how it turns out though. As a sandblaster I can assure you that it will be cheaper for you to use a stripper before you take it in to be blasted. Quote Link to comment Share on other sites More sharing options...
BusterZ Posted November 4, 2003 Share Posted November 4, 2003 I have done CO2 blasting on stainless steel pipe at a refinery to prep for chloride resistant coatings. Worked OK, but not as well as traditional 'black beauty'. Used CO2 to eliminate possibility of sparks due to combustible materials in the area. Seems like it should work on undercoating. How's the cost compared to regular blasting ? If this worked, I'd be interested to use on my car (if I ever get that far). Quote Link to comment Share on other sites More sharing options...
zgeezer Posted November 4, 2003 Share Posted November 4, 2003 If your talking about the stuff Nissan placed on the interior of the Z, buy a bag or two of dry ice chips and place it on the floor. Wait 10 minutes and attack with small hammer and a stiff putty knife or flat chisel. The stuff will pop off in chunks when cold. If you like high tech find a co2 fire extinquisher.
