Taking Bitumen off from the body

Hi folks,
I was asked to wash my co-worker's cars (a mini van and mazda 3). As the mini van is still pretty new so it required me very less effort. But after I have done the mini van, I realised that there were million of Bitumen spot sticking on the door panels and the rear fenders. The owner explained that the bitumen came from the newly paved roads in his neighbourhood, and he has offered me to take that off using WD-40. I refused his offer as I was concerned with the safety of using the product on the paint.
I am thinking to use clay bar or CCG foam wash, any better ideas?

 

Plain old kerosene will take it right off.

 

Thanks. But where get I can that if I live in Canada?

 

hahaha

really?

go to canadian tire!

 

3m adhesive remover, stoner tarminator, autosmart tardis, chemical guys grime reaper, etc...

 

prep solvent works wonders on tars . it breaks it up in seconds without harming the paint
