Now 6 years and 180,000 miles later, they show no abrasion loss from the occasional scrapes accumulated along the way.

You'll need to keep a coat of paint on any coroplast that is exposed to direct sunlight, otherwise the sunlight's UV will cause the coroplast to become brittle and crack within 2 to 3 years.
Thanks. There's really just one speed bump I'm concerned about. I actually parked over it and measured the clearance before making the skirts. I think it should just barely clear if I go over it really slow. I will stop over it and see how close the skirts are.

I never even thought about sun damage, I just didn't want 7" wide white bands under the car.
