I've got the static cling ones from GoChecker... they're great... Ive got at least 5 years out of them and still going strong. Car started as a dedicated track car and is now a SpecE46 race car. I leave them on all the time...occasionally used to pull them off if I need to change the numbers for any reason (different clubs, etc)... They adhere well. The trick is to keep the backs clean, and apply to a surface that does NOT have heavy wax or detailer. Wiping the spot where you plan to apply them with a damp rag and dish soap works well
