Oh,i have used the durabak product on an EPA
research boat that we rebuilt as well as on the sole of a 17ft
aluminum fishing boat,im pretty impressed with it although we found it a little hard to keep clean, they claim that it is even grippier wet so if you need non skid that actually works this stuff delivers. I have not heard of anyone using the bedliner on the bottom of a boat,i dont know if it can be applies suitably smooth,if it was as textured as a truck
bed there would be too much drag.
