I plan to try out OS on a polished jet black car.
It currently has Zaino on it. The *test bed* will be a part of the car that I will remove the Z from it.
Durability wise, is there going to be a difference with Optiseal on bare paint as opposed to either a:) acrylic glaze like CG/Danase or b:) CK RMG . I'd be more incline to try the glaze/OS combo ;-)
