Topside paint question (coverage)

[Jeb]

I apologize in advance, because I'm sure this has been covered, but I searched and couldn't find an answer. How much topside paint will I need to cover the deck on my V20 Cuddy? I'm thinking of using the Rustoleum Topside paint on top of the Rustoleum Marine Primer.

So - whaddya think? How many quarts of each would you get?

Also - I'm considering either using the rustoleum non-slip additive, but I'm also considering not using anything. Even after being covered with a couple coats of old topside paint, the deck has substantial teeth to it. I feel like the existing texture would probably be enough texture. But, I'd love to hear your thoughts.

Thanks.
