I wouldn't use awlgrip because it is veeery slippery when wet... even with nonskid mixed in. A friend of mine had his 23' recently rebuilt with awlgrip/nonskid and i almost fell over when the decks were damp in the morning. I have had trouble keeping my footing while out fishing too, so in my opinion: awlgrip meant for a clean looking/shiny finish (hull)- not nonskid. I would also use GELCOAT. Try cook composites- they wholesale most likely to someone in your area and carry a full line of gelcoat products.
