Reflex protects against abrasion, dents and resists gasoline, diesel, oil, chlorine, fertilizer, acid and salt. Even in severe freezing temperatures, Reflex retains its rubbery surface and will not scratch or damage what you put inside. Because of the rubbery grip your cargo will not slip-n-slide as it would in a plastic drop-in liner or hard spray-on liner. Reflex means protection for your truckbed and your cargo.
