I did my decks and cabin top in the spring with Kiwigrip mad it came out great. As with everything tomdomwith painting, the results are all in the prep. I washed, abraded, washed again, then solvent washed to get the best adhesion. Now that I see how tenacious a bit of spray is on non-prepped areas, maybe I needn't have bothered being so thorough.
Careful masking is crucial to good results. A helper is pretty well necessary. Slop it on with a small notched trowel and float it out before rolling. Different textures/grippiness can be achieved by varying the a punt of product and roller pressure.. Pull the masking tape right away. Kiwigrip has a chart for heat and humidity, well worth looking at.
I was lucky to have had one perfect day this spring, warm, not hot, medium humidity, we just roared through the application on my 32 footer.
I also did a custom sort of sandy tan color at the local paint shop. The contrast with my freshly painted cabin top and cockpit is fantastic.
It will cover roughly what the can says, I think it's 80 sq ft per gal?
