Re: What is something like rhino lining i can do the floor of my jon boat with?
The hercu-liner mentioned previously works very well, I've used it on a fiberglass boat deck and it is very durable, two years in and not a scratch. It comes in gray, white, black and red i believe, the gray is a darker industrial gray, not a light gray. Two coats gives a more uniform texture.
Also resists gas, which is a big plus on a deck.
