So maybe you should have pointy white sticks on the front and back of your car. LOL
u do realise you have annoyed

about at least 45% of people readin this.
but i Recon everybody has kissed a bumper in their time and not told anybody.

Imagine walking around, asking people if the PARKED car you hit belong to them. LoL

i've come back to fid broken doormirrors/scuffs/scratches/dents on my cars in the past. or i've noticed them while walking to the car on my driveway the next morning.
Currently, i have painted bumpers, but a thin Plastic un painted part touches first.

& i always make sure it has Tyre gel on it, so it doesnt pull pait off if it is touched by another bumper.
