Well, it's been about two weeks since this happened but I figured I'd ask for ideas. A plastic shopping bag must have blown under my car in a parking lot and got stuck (melted) onto the heat shield of my 2nd cat. Tried to scrape as much off when I found out about it but it was pretty burned on. I figured it'd take a short period of time to burn off but it hasn't and it smells like shiat. Any ideas as to how to get it off?

 

Wd-40 ?, Plastic cleaner , Silly string ?, Hot Soup?

I dont know , bad luck.

I recently got a MILK jug , 1 gallon by the way stuck up behind my front left tire, some ******* left it in the middle of the road.

If its melted on, maybe just give it some time to wear off.?

 

Try using Acetone. It'll remove almost anything. It does eat rubber, ruins paint finishes and smells potent , so be careful.

 

I wouldn't worry about it.

My Trans Am used to sweep the highways clean of plastic bags. They always stuck to the cat too. It just burns off after a while.
