I've heard of many uses of ceramic coatings on top of clear bras, but never the other way around. I'll assume that probably because the clear bra has trouble adhering to the surfacing of something that is hydrophobic. But are there any high quality ceramic coating that can be applied just before the application of a clear bra? Maybe something that doesn't have such a slippery surface?
I'm asking because I'm weary of a clear bra that is left on the bare painted surface of a car panel for years (maybe even more than a decade) in a place with very hot summers and very cold winters (so pretty strong temp variation, expanding & contracting). My current Mazda3 has had its clear bra (Protex) on since 2014 and it still looks great. This question is about a future car I'd probably buy new.
