Yeah, I bought one 
Did correction then 2 coats of CQUK3, but I didn't do the roof as the entire thing is glass.
Since the coating is supposed to bond with the paint and there is no paint, I didn't think it was the right product to use. Or is it?
I know Carpro makes a windshield product but this isn't a windshield.
Would something like Aqualpel be a good choice?
