The 3M Crystalline 70% is undetectable with a careful install and showing your stickers correctly with no rips etc in them.
I used some plain/clear static cling clear vinyl (like your oil change stickers) for my stickers. I just got new inspection/registration stickers and stuck the on the vinyl and cut them out. Bingo.
