Ceramic coating Paint sealant

[CornHusker4Life]

Has anyone had this done to their car's paint before? My brother is looking at getting it done and was wondering if anyone had any experience with it. It will be done to a new 2018 duramax dually. The 3m clear bra guys dont think they can get the film to lay down properly on his dually fenders so they suggested this ceramic coating.

Thanks, Jarrod
