Thanks for the advice.
I am in the pre-designing phase and was just wondering if anyone had ever used bedliner before.
I will probably go with a proven method but just happened to think about using the stuff after seeing it in someones truckbed.
As far as the water requirements go, I own a water well company so all the scientific equations to make it work, I can take care of.
Again thanks for everyone's advice and any more is appreciated
