I asked a body shop friend and he said there is no consumer chemical for this really. Some use torch to burn out the residue, and gasoline will break down some brands. Back when Sears was around, my brother and I got one of those hopper-style sand blast units and filled it with actual sand. We sandblasted an entire F150 on a dirt/weed patch next to the driveway. If memory serves we linked two compressors together, and it took off everything -- Bondo included. That was easily 30 years ago, and we had no clue about the dangers of silica in real sand, but you can get silica-free media and go to town. If you put down a tarp, you can ever re-use some of it. Or just take it to a media blaster....

Omfg. Id say it’s not ok for any car to look like that.

That picture looks like it was taken at PittRace. I actually raced with that series (chump car?) at Mid Ohio about a month ago. That was quite the experience…can’t say I desire to do that ever again

Yeah. Champ Car. I raced at Pitt. Those cars are terrible. They’re changing the rules for ‘23 to not allow that anymore is what I heard.
Interesting, given the clientele that series attracts I can't imagine they will have many entries if they stop allowing that. Unless they just turn into another AER/WRL. WRL's entries selling out in < 2 minutes is super annoying so I suppose another series closer to the likes of AER/WRL would be cool...

Thanks for asking your body shop friend. I'm going to call a blasting company tomorrow. If I get a good feeling talking to them and the estimate is <$1k I think I'll seriously consider going that route.

You might also search for mobile dustless blaster. I just googled and see that there are a lot them (around me anyway). Might be easier than taking it somewhere. And, you'd be able to prime it faster to avoid surface rust, which can be a real pain if the car sits a night or two before you get it back after blasting.

I found these on line:



Heat might be risky...
Have not tried them myself but thought they might be helpful

Yep I think that’s what I’m going to investigate for now

I have raced in vintage for 25 years. It pays no money.

In fact, it's the old saying: "If you want to turn a large fortune into small fortune, you should go racing".

I like your tech and workmanship videos. No doubt.

Ascthetics aside, can one simply 'paint' over the stuff?
