My truck has never been clean enough to apply a sticker, but the canopy has one. If I put one on my boat it would capsize. (yeah, its small)
Got one on my work truck though, and I have one in a peculiar place holding a broken seam together on my rain pants. Almost time for a new one since it has been half torn off intentionally many times. I guess you could call it my "FLIfish" sticker.
