take off tar type undercoating?

previous owner put that tar stuff all on the fire wall. looks like crap. i been getting this orange citris stuff from work that cuts it pretty good. but i can only take so much. and i talked to the guys that buy it and they say it comes in a 55 gallon drum and is like $1500. so, any ideas about some other stuff.

 

dry ice. it will harden like a rock and flake off with a plastic putty knife

 

I wonder if CO2 freeze spray would work then ... advanced auto hd $1.77 engine degreaser will work if you have a power washer . it safer's than Super clean... and oven spray

 

Being from a state that uses a lot of salt on the roads, we see Quite a bit of that undercoating stuff on older cars. The best way I have found to remove it is with a heat gun carefully( you don't want to warp the panels) and a putty knife or wire brush of some sort. Good luck its always a hated task.

 

go to auto paint supply store they carry a remover for undercoating one brand is "under off"

 

I used a heat gun and scraper to get the worst of it off and then finished it off with paint thinners on a rag.

 

2 cheap helpers, 2 putty knifes and 2 cases of beer.LOL Seriously, the stuff at most paint stores to remove that crap is good. Used it one time to remove undercoating and it just kind of desolves it. Don't remember the name but I remember where I bought it. Crappy job. Thanks, BOBBY FORD

 

Been doing some fabrication on this guy's 69 SS 396 Chevelle and he shows me this tool from Snap-On that HE used to remove the factory undercoating from his project. He said he tried ALL the tip's that we all use without much progress. He bought this tool and now swears by it. He said it takes it off like magic. I personally did not try it; but I seen where he did. It cleaned it right down to the bare metal. at $414.00 List (No idea what the Snap-on man charges) it's a little $$$$. I know I would have paid that price to use on my Fairlane. Scraping undercoating/body sealer sucks big time. I added a picture and a Part# PT280THUGA for those interested... Rob

day laborers

 

At the body shop I used to work at, I'd heat it up with one of those little MAPP gas torches, just enough to soften it up and then you can scrape it. Heat gun would probably make it easier.

 

hahaha
im likeing the beer and day labor idea.

ill go to the paint store and check out that stuff. thanks alot guys.


my grnadma actually told me to try dry ice though. i think she was kidding but still. weird.

 

I had luck with WD-40 once. Just spray it down and let it soak in and it scraped right off.

 

Heat gun and a scraper. Then you can wipe off the residue with lacquer thinner.

 

Brake cleaner with a stiff bristle brush and plastic scrapers works well- my '70 Nova firewall came up nice and clean.

 

Yep! A friend of mine uses this method , and swears by it. Cheap, too!

 

Ive used a rag soaked in kerosine, be sure to light a smoke first.

 

you can buy that same wheel at some hardware stores for alot cheaper....you just mount it on your angle grinder...
