Ceramic coating your paint?

That 50ml bottle is $60...wonder what the coverage is like?

And yes, they stress that the paint must be clean and buffed prior to application. and 48 hours of NO moisture.

You should get 3 cars out of a 50ml bottle. It goes on very thin. And prep is the most crucial part. Any scratches or swirls in the finish will be sealed in. I would recommend using Gtechniq C1 and top it with 2 or 3 coats of Gtechniq EXO. Exo is a Hydrohobic coating and anti-static with will keep the dust down.
