307 plastic parts paste polish remnants

hello friends last week a friend of mine polished cake to 307 everything was great I made the first wash at the auto wash today, I saw that there are remnants of black and white lacquer on the bumper and door side, is there a way to pass this? I apologize if I opened the issue in the wrong place, I'm waiting for your help, thanks in advance. the raconc 2014-11-11 21:25:40

synthetic thinner - isoporpilalkol

Doesn't it harm if my teacher comes across thinner paint

does not give synthetic. takes cellulosic paint.

Where can I find isoporpilalkol?
