The bumpers can rub the paint if you stick them to the deflector instead of the hood.

I know it seems like a good idea, but sticking the bumpers to the deflector will have dire consequences. Besides, the little sticky bumbers will come of the hood with very little fuss if you decide to take the deflector off.
