Thanks for the help guys, that dried on wax remover looks promising if I can find it here. Yes I know I should have masked the car but I just got the orbital buffer and was anxious to wax this thing since it was one of the few cool days we get in the summer.
Lots of things to try, I would have to try some goof off in an inconspicous area to see it it melts the plastic. I will let you know how it works out, I'm just amazed at how tenacious this stuff is. It has been pressure washer within an inch of its life over the winter and has not moved.
