I'm writing this to ask if anyone out there has a tried and true way to remove the black Ziebart undercoating? My car has about a 12 yr old application, and I want it off. I called Ziebart and he said maybe try some mineral spirits. These are things I thought of.. Give me some feed back.

1) Goo Gone (Applied with paint brush and let sit for an hour or two, then washed off)

2) Power Washer (An actual power washer, not a car wash)

3) Mineral Spirits

Please help, I want this cracking, brittle crap off of my car!

 

We used a propane torch & scrapers on my bud's '62 truck,, the undercoating was on thick & rock hard. Just get it fairly warm (not burst into flames hot) and it should peel easily with a scraper (or putty knife),, the remains can be cleaned with something strong like laquer thinner, acetone, etc.

Your best bet is to use a heat gun, it is safer than a torch....the it is the same from there....scrape!

Well im in the same process, its a royal pain. I want all that crap off of the car. So far i;ve done the one front wheel well and about half way back under the car on one side. Its taken about 3 hours id say, but i just learned about the torch during my experimentations, and boy does it ever do wonders. If only i would have checked here sooner.
Let me know how you make out, and i will too. Its a long process but i think the rewards will be worth it.

What i plan to do after scraping as much crap off as possible is taking some heavy duty degreaser/cleaner, soaking it, then getting under there with a high pressure washer to clean up whats left.

Good luck

I've used it and there is still a lot of scraping involved and the scraper you get with the kit doesn't let you get to all the contours of the wheel wells.

Well i got as much scraped off as i could, then through on some degreaser and pressure washed for an hour today. Im satisfied with the results i guess, but i still think it could be better.

Im gonna go to a hardware store and get some contact cement cleaners....i remember when i worked in the lumberyard we used it to get roof tar off, so it might just do the trick to clean things up abit more.
