Get off your high horse.

If people don't want to put shit on their car that will damage their paint more than they are already subjecting it to, there's nothing wrong with that. Tape always comes off....magnetics fall off half the time. Shoe polish is good. Doesn't come off. You can go over it twice and make it nice and dark and thick so it can be seen well. Does no damage to the car.

I don't know who you think you are, but it's certainly nothing good.
