I bought a new car last week and my wife drove over some recently ground-up-in-preparation-to-resurface road.....i can't describe what kind of residue was on our brand new car
she was going to wash it off immediately but didn't get to it until today.
it didn't look like tar due the amount of dirt in it but it would not come off!
i used the turtle wax bug and tar remover and it crushed it!
very pleased with the results and wanted to pass along some info/
cheers m'dears!!
