What is the best way to remove undercoating?
I need to get the undercoating off, from the wheel well. I will be welding and am sure I need to get it off. What is the best way of getting it off.

I just did a big part of my undercarriage with putty knives. 5, as they got dull I just grabbed a new one. A wheel well is more curved though. I just saw some undercoating remover spray at autozone or Oriellys. Not sure which place it was.

^^^This. Removing undercoating is an awful job. There is no easy way, short of dipping the entire body shell. You can't media blast it because the resilient nature of the undercoating absorbs the force of the blast media. Depending on how thick it is, you might have some success with oven cleaner.

I have a feeling it is to thick for oven cleaner. It might be 1/8 inch thick. I was hoping for a magic bullet. You know spray on wait 30 seconds wipe off with a paper towel and be done. Heat and putty knife here we come.

I did the entire underside of my car with an inexpensive quartz work light pointing up at the undercarriage. As it heated up an area about 15" square I would move the light over and scrape it off with those inexpensive plastic putty knives. when I was done scraping, the next area was soft and ready.
I used the chemical undercoating remover for cleaning off the little bit that was left on the paint. Mine was Ziebarted and the chemical stripper did nothing to remove it. I had to scrape it all off.
After that, I just scuffed the underside and sprayed it.
Although you got the undercoating all over yourself when you were working under the car before, and it was a bitch to remove, I have to give it credit, it worked. The only holes in my floor pans were from the screws I put there to mount my amps under the seats 30 years ago.

I went through this process with my 442 and now am cleaning portions of my convertible. I use Easy Off oven cleaner and scrape and wipe it off with plastic scrapers and rags and finish off with varsol. Messy procedure but it works and the results are worth it.

I used a heat gun and various scrapers. Was even able to get the seam sealer that seperates the inner and outer wheel well out clean. I did have it blasted after but was pretty much to paint prior to blasting
