caddyshack Posted April 1, 2014 Share Posted April 1, 2014 I've got a '69 SS Chevelle convert with 22K miles that needs the same removal. It will be interesting to hear the responses. I tried just about everything; solvents, grinding, blasting, etc.. You can't get at the double paneled areas. Luckily it's so old that the undercoating does not soften up in the heat. A fellow collector told me that he dipped his stripped down auto and got good results. Good luck, I could use the same help. Link to comment Share on other sites More sharing options...
old car fan Posted April 1, 2014 Share Posted April 1, 2014 On our 47 Lincoln,we used a Dremell multi tool.No solvents,just greese,elbow greese.Great tool,with many uses. Link to comment Share on other sites More sharing options...
Bhigdog Posted April 1, 2014 Share Posted April 1, 2014 Easiest method is a Bernz-O-matic torch and a putty knife. Once you get the method down the coating peels off in long curls. Finish with a kerosene or other low flash point solvent.............Bob Link to comment Share on other sites More sharing options...

jackofalltrades70 Posted April 1, 2014 Share Posted April 1, 2014 I was able to remove most of mine with an air powered needle scaler. It will reach into a lot of the crevices and remove the hard/stuck of stuff.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Lahti35 Posted April 2, 2014 Share Posted April 2, 2014 I also found this to be the best way. Lay cardboard down to keep the floor clean....and keep the doors and windows open (in the garage, not your car)! Link to comment Share on other sites More sharing options...
28 Chrysler Posted April 2, 2014 Share Posted April 2, 2014 A heat gun and scraper also works and is a bit safer than a torch around fuel tanks and rubber hoses. Removing under coating requires 2 hours of clean up for every hour of removal. Link to comment Share on other sites More sharing options...
Amphicar BUYER Posted April 2, 2014 Share Posted April 2, 2014 We use the heat gun or torch method with great success. Be careful and you will make quick work of it. If it's not really hard the needle scalers will only beat it down, but not remove. They work ok if it's brittle enough. Link to comment Share on other sites More sharing options...
DavidAU Posted April 3, 2014 Share Posted April 3, 2014 I guess it depends on how hard/dry the undercoat is. I tried the head gun and scraper method on my 47 mercury and found it melted the coating and although it was coming off it I would have to clean the steel with thinners to get rid of it so I tried doing it cold with a sharp wood chisel.It was dead easy and was all off in about an hour and a half.

caddyshack Posted April 3, 2014 Share Posted April 3, 2014 Thanks for the tips. I am going to try a couple out as soon as it warms up. Maybe I should have hit it with a hammer when it was -25 this winter. Might have cracked like an egg shell.Thanks again. Link to comment Share on other sites More sharing options...
