I used awlgrip non skid on THE OTHER BOAT. The best method was to broadcast after rolling and tipping. The base coat needs to be as strong as possible because it will hold the grit. My guess is that some reducer will help the paint set up strong. For awl-grip I used a sheen killer, and overcoated the grit with more stuff to lock it in. The overcoat should be reduced way down to keep it from filling the grip pits.

Awl-grip extra coarse is wicked rough and terriffic non skid,
Awl-grip medium was great for something you must sit upon
