Dmax that's all there is on any floor. Sliding parts in the bed of the truck, driving around with five gallon buckets sliding back and forth on every corner. Even a shop floor gets abrased every time someone drags their feet on it. The air creates abrasion on the side of your truck when you are driving down the road, it may not necessarily be the air, bu th floating particles in it. Want proof, put a new windshield in, and pay close attn to how clear the bottom part of it is. Abrasion exists anywhere two things come in contact. I don't never anything about super ultra dry, but if abrasion is it's number one enemy, seems it would not be useful anywhere two things come into contact, I guess it depends on how abrasion resistant it actually is. I would think the bed of a service truck that is getting used well would e a high abrasive area. Just saying.
