I have never heard of anyone using that stuff on a boat.
You may be the one to test it.
I dought the shine would be very good.
Some have used Rustoleum on there boats.
The home centers have that.
I have heard of people using the 2 part garage stuff in the bilge, but not on deck. You probably want something with a little less sheen to it or you are going to blind yourself on a sunny day
Allot depends on what you want from the paint job you are doing.
A true marine polyurethane paint is going to have UV protection in it so that the sun wont cause damage and fading of the shine. A good marine paint will also be designed to level out when properly applied so that when it is dry it is very smooth.
I doubt floor paint will have those characteristics.
I agonized over having to spend the big bucks on marine paint the first time I bought it. But I do not regret spending the money.
