I have a machine silver car that gets streaked from hot pieces of soft compound tire coming off the track. The car ends up with black marks and streaks everywhere that are very hard to remove even with multiple coats of Zaino on it. The stuff looks alot like tar and is about as hard to remove. I am wondering if there is any product that might make the paint easier to clean. I am not so concerned about looks for this application. Maybe Pam! lol
