polypropylene material?????

I emailed a couple ebay sellers and some say there bumpers are made of plastic and one says polypropylene. Is that better then plastic or rubber bumpers.


Need to know so I can buy it by Friday!!!

P.S. Also what are the bumpers made of on the 93-97 camaro's from factory?

Be careful of the bumper covers on ebay. Word is they don't fit right. Go with a GM cover. There are some posts about this topic.

go with GM. find one at a yard.
