Just go to a coin wash, put in 5 bucks, blast the car with high pressure soap, then hit it with the soap brush, and repeat this a few times, you should be able to get it off with this technique it works for me, then after its clean, you are going to have some sore arms after all of the waxing and buffing you are going to have to do to get it shiny again lol....I am thinking like 4 coats of wax....mMMMmmmMMmMmM
