I have used sand mixed in with paint. Used it on our hay wagons. Works excellent. Nothing funner than trying to hang on for dear life while going up/down hills and stacking hay too!!

I like oils (don't mean oil paints either) that soak in for the simple reason it won't peel up. But don't know if that is to feasible with plywood. Is it an outdoor/marine grade ply?

Astra turf?, but that may hold moisture to promote rotting the wood.

edit-- esshup reminded me that when I used sand, I dusted the wet surface after the paint was applied. Not mixed in the can.
