I currently have a drop in liner, over the rail. Its pretty nice, afterall it really cleaned up the truck. I also put a piece of plywood in the bed of the truck to protect the liner itself, and it hellps to distribute the weight, and its nice to because it creates a mini ramp. Anyway, the last time I remember looking at the bed, it had quite a bit of waves in it. Will a rhino lining go over those waves okay? I would stil put the plywood back in over the waves and lining to protect it, and distribute the weight. Any ideas?

 

Rhino Lining is spray on isnt it? If it is I dont see why you can't spray over the waves. It might not look that good but it should work. If your still concerned why dont you give Rhino a quick call, or try looking for a new drop in liner instead.
