When I was growing up everyone ha a car bra on their car. I mean it was one of the first things you have to get for your cars. Now I never see them on the road anymore. Probably one reason was all the dirt they would get underneath them and scratch your paint up. I don't know why did more damage the rock chips/bugs or the bra itself. Strange though, I haven't seen one on a vehicle in years. What a strange trend.
