Re: non skid deck paint
I'm going through the same process. I ordered some samples from Durabak to see what its about. At first I considered doing the paint it and add some texture to keep the cost down. But the more I have worked on the deck, glassing & and sanding, I figure I might as well spend the money and get the durable (yet more expensive stuff). I've asked the question and there have been various things people have used. Such as Grizzly Gripz, Duraback, Kiwi Grip, and Rustoleum Deck paint.
I guess it all depends on what its worth to you. The more expensive appears to be longer lasting and more durable. Lower cost, less durable and lasting. Just like everything in boating, go with what your budget can handle.
