Coop, I don't think it will hinder you in the water too much, but would be concerned with driving over obstacles. I thought of coating the outer of the trackster, but decided against it. One of my brothers has it in the bed of his truck, take loading concrete blocks for example, set it in, then get in and move it to the front, nothing slides on it. I can't help but believe that it would have the same effect when going over mud, limbs, logs and such. Now as for the inside of the tub, heck yes! Again, nothing slides on it- even when wet...
DESTRUCTION is just a couple of vowels down the street from DISTRACTION
