I used the 50 yr advantech for the floor in my boat. Held up great for year 1. 8) 8)
B4 my lay-off ,I worked in a Paint /Industrial Coatings supply house. What you are looking for is a product from California Paint (andover mass) called Tuff-quick . It`s an oil-based semi gloss paint available in whatever color you want mixed. Lobstermen in the area buy it to paint thier boatdecks and lobster bouys. I painted the bottom of my aluminum bassboat with it to seal up few leaks . Year 2 now -no wear other than beachin wear. You can mix non-skid additive to it (beach sand basically). Takes forever to dry , so plan properly or do it in the garage. Just make sure ya open all the doors and run a fan. Wearing a decent mask with filters is a good idea also. Have some paint thinner on hand for cleaning of tools and spills etc. Call your local paint dealers and find a California dealer. Buying "Marine " paint is a waste of cash. Ask the lobstermen, they luv the Tuff-Quick because it`s bullet proof and far cheaper than any paint labeled "marine".
Everytime it rains like this I think about putting on rain gutters, maybe this summer.
