The only possible product that actually works as a sealant and gives a crystal like protective layer is Gtechnic but its a product that takes some precise application.
Ive been looking into offering this as a service for a while now and had talks with Gtechnic about it, sounds and looks excellent stuff but will be costly on supply and apply and there will be the need of 18month intervals to take care of it by the specialist whom applied it.
Im thinking the f1 stuff is a product designed like duragloss road and track polish, suppoesedly enhances aerodynamics :?
