hoping someone could inform me on the use of Crystal Guard on my 04 twilight blue coupe. Does it matter that I had the teflon coat put on at purchase? What would be the best at this point? thanks in advance!
Happy Halloween ;-(

 

I believe that the CG will bond with whatever clean coating / surface it is applied to. For example, CG states that it can be applied over a coating of wax, but that the life of the CG will depend upon the durability of the sub-layer. You should probably also try contacting Jim Campos at CG to ask him directly. He is pretty good at responding to e-mails.
