I haven't had a lot of succes with the spray on deck grip, they don't seem to last. I did the sugar treatement on mine and it was sweet!
I just painted on a layer of surfoboard resin (which doesn't yellow, but it's still noticeable) sprinkle on the sugar ( caster sugar is the best size) and you're set. I've been told that automotive clear coat does a good job as well, and that's available in a spray can so easy to apply.
