I just put 3 coats of Z2 on my car with ZFX 3 weeks ago. I need to strip the front hood and bumper to apply a clear bra. Will Isopropyl Alcohol do the trick or can that still leave some behind? I've read conflicting posts on if Dawn will remove Zaino. I suppose i can spray it down twice with IPA and then spray some water on it and see if it still beads.
