What is that tar like rubber in the rear wheel wells. I was thinking it was some kind of sealer sprayed by the manufacturer. I don't have a new car to look at so maybe someone can help me out. I want to know if I have to scrape that gunk out of there.

 

Jack the car up and look underneath as the whole underbody of the car is covered in it. It's just underbody sealer type stuff. It's also a ***** to get off of your clothes & skin.

 

The funny thing was all the "tar" that I had on mine was finely shredded Advan rubber

 

its stuff mitsu sprayed to protect it from the salt

 

it's called undercoating.

 

yep and if you scrape it off and say, oh **** later...check out waxoyl. that's a quality product.

 

do a search... there are all kinds of post on the stuff
