Its almost half as thick as a pen...
Same height as a shopping cart, no dents though... Think I would have noticed at the store seems how its on the drivers door, think a bum did it when it was parked overnight, I think I will get the double sided touchup paint pen and see what I can do.
Now when I go to the store and see the rubber bumpers on the corners of the shopping carts I breathe a sigh of relief....
