Nope It was raining round 9am this morning and I saw the liquid come from under the truck, so I thought is was most definitely oil or something of the sort. Because I have been sprayed by oil before and it came off no problem.
I figured it would come off in the rain or I could just wipe it off later, I had no Idea it would dry like paint and stick to my car. If I would have known at the time I would of followed the driver and explain the situation and got his information.
