If the part is coated with such a resistant release agent then not only will the 3M tape not adhere, nor the wrap, you'd have a hell of a time painting it as well!! I didn't realize it had such a coating but figured I'd thrown in that "body shop prep solvent" just in case. Besides, I'm the guy who polishes the paint after it's applied - I don't prep surfaces for paint, nor do I spray the paint.
