Not sure what it is, but I've got some tenacious black goo that is splattered in my wheelwells and on the inside of the mudflaps, it has "set" and is pretty hard now, but still "tacky".



It may be tar, its really chunky though. The PO did it, it doesn't look like anything I've seen before.



What is some really strong chemical cleaner that won't ruin the plastic mud flaps?



I plan on scraping off as much as I can first.



Any other ideas are also welcome! :thx

If it's tar like then hit it with some mineral spirits and it should take care of it with some patience and persistence.

I'd use AutoInt's New Car Prep, but the mineral spirits probabl won't hurt anything (I'd just rather be sure).

Typically new car prep solvents are a blend of mineral spirits and other components that are a little more aggressive. Mineral spirits is probably one of the least aggressive solvents you can use on a car. 27 years in the chemical industry and formulating many blends over the years has lead me to this conclusion.



Just checked on the msds for the new car prep and it contains a blend of low and high aromatic mineral spirits and and also about 20% of high flash aromatic solvent. It would make a good tar remover and more aggressive than just mineral spirits alone but also would have a lot more odor to it. Being a blend would also likely make it more expensive than mineral spirits from Home Depot or a paint store. If a person can handle the odor then it would be a very good product in that application and like any solvent, one needs to make sure they wax any panel that it comes in contact with as it will strip any wax.
 
Meg's Body Solvent. I had similar rock hard tar chunks stuck on my work truck when I got it. I assume they had been there for years given how set they where. Body Solvent and a terry cloth towel took care of them in a couple different sessions.

Ah, I learn something new every day! Didn't realize that the mineral spirits were *less* aggressive, even though I've used both. Thanks for the info.



And yeah, the New Car Prep does have a bit of an odor to it, I'm probably used to the stuff.
 
The mineral spirits removed the top layer of black sticky goo.



Once that was removed, what remains is a rocky asphalt type concoction, it is rock hard, I need something ALOT stronger.



Should I move onto the Megs' Body Solvent?



Thanks!

It would be worth a try but if it's rock hard there may not be anything that will penetrate and soften it up. The key is to get something that will soften it up and then wipe it off before the solvent evaporates and the substance hardens back up. Keep the rag soaked and continue to wipe and see if it softens up. It will likely take patience and working it slowly to keep from damaging anything. Be sure to apply some wax to any surface the solvent comes in contact with as it will remove any wax and protection.
