The Stovebolt Site Forums The Shop Area Paint and Body Shop undercoat removal

Any secrets to getting the black ooze off the
undersides of my '54 GMC? Grinding with a 3M
disk seemed to smear it around and cover any
exposed body parts with airborne sludge. I tried a citrus paint remover but 1) I hate to use chemicals 2) its hard to drink a beer with a respirator on. My hood is too big to fit into my blast cabinet. Suggestions would be greatly appreciated.

Eastwood company has a product called "Undergone" #31130Z that has worked for me.

There is no easy, quick way. I heated about an 8 inch square area at a time with a handheld propane torch. Just enough heat to soften the undercoating, then scraped off the undercoating with a putty knife. Takes some time but did a good job of removing the old undercoating. Of course, I had the cab off the frame resting a the firewall on a cab dolly, made musch easier to get to.

I had to do the same thing. The stuff from Eastwood wouldn't touch it.

I had to remove a bunch of undercoating when I worked on my truck. I did not find an easy way to remove the stuff. I used different techniques on different days. Sometimes I felt like sanding, sometimes I felt like gooping it up with paint stripper. Other days I felt like grinding with a wire wheel or a fiber 3-M stripper disk. Some days I used a stiff putty with a sharpened edge.

After many days of trying everything, one day I went out to my garage and the undercoater was all gone. Good Luck, it is tough stuff..
