I dont believe that it would be as slippery when wet you can get a qt of herculiner and add a sustance that is called silca it is used on floors you add it to the paint in high traffic areas that are wet often. I have herculiner in my truck bed and it is NOT slippery when wet. the added sand (silca) is a dark grey and works great .
i paid $89.00 for a gallon of the herculier not sure on a price for a qt here is the web address
