There is a posting somewhere, (I can't find it now), that showed a shattered sport bumper. The guy'd mistakenly hit something just a bit, and it was shattered.
I was AMAZED. It looked from pictures to be a big tough piece of hard rubber, and I'd never have guessed it was a fragile, hollow piece of plastic.
NO, I wouldn't pay the $500 for that....
I'd like to find something very simple, that protruded just enough to protect the bumper, like a rubber pushbar, that just had two vertical hunks of rubber, that could take a bit of a beating.
Someone said Pep Boys sold something rubber like that.
