Filled in matt black, which foil? Other tips?

Hello, after careful consideration I will stay with my Renault Megane CC for the time being, also because the problem with the constant flickering of the xenon light has finally solved itself (three times-on-wood-knock…). However, he gets (Spanish-red, stainless and without dents or deeper scratches) a fresh cell cure in the form of a full foliation on the color matt-black. Now I have already inquired a little and also in my vicinity two relatively good workshops, which would make the folation. However, both with a foil of 3M (with guarantee of 3 years). I have now read on a forum page that some probably use ORAFOL films, because these would be supposedly more durable (up to 7 years)? If I am ready to invest now, then I would also like to have more than 3 years of it… Does any of you have any experience with foling in general and with the two slides? What would you recommend me and what should I pay special attention to? Thank you for your tips in advance and many greetings, Tom
