Topped off a cream colored car with Collinite 845. Knew I had put too much product on when I felt the resistance in wiping/buffing off. The next night, under incandescent light, at just the right angle, I can see the path of my application. It's like I didn't buff it all the way off. Hand rubbing/buffing doesn't remove it. This only shows up at night under the lights. Should I try buffing with the PC with dry gray pad? Or with bonnet, or what?
