Go to hardware store, get magnetic air vent covers and put sticker on that. Cut magnetic vent cover to fit sticker and then you can put it on any metal part of your car just like those ribbon magnetic stickers you see on cars all of the time.

Only thing you need to worry about is going through a car wash or somebody pulling it off your car for theirs or to throw it away.

Every time I go through our local car wash (uses brushes) they take off my magnet stickers and place them on my dashboard. After they get done wiping off the car, I put them back on.

Speaking of stealing stickers. In 2004 we had a rash of that in our town. I had several yard signs in my front yard. I simply linked all of them together with copper wire and metal clipped them to each sign. The wire was, then, linked to my yard lamp post near the outlet box on the lamp post. The fake hookup was not live and posed no safety problem BUT the punks didn't know that. Kept my signs up for a month without any problems. Others in our subdivision got theirs stolen though.
