shoot Awl Grip all the time. Its a polyester polyurethane and not recommended for underwater.exposure by the manufacturer. I take that to mean prolonged exposure. It can with stand a weekend in the water usually with no problems. Any longer than that and you start running the risk of surface release and bubbles will start to form under the paint. I have seen this alot along water lines of boats that had the sides sprayed in Grip. You just need to be mindfull and limit the exposure like my fellow Pensacolian Adrenalin Junkie has done with success.
It is also not recommended to put Grip on the bottom if the boat has ever had prolonged in water exposure. The boat would need to be thoroughly dried out before applying any paint other than AF paint.
Interlux Performance VC is a good paint for your aplication..It is not a antifouling paint. It is a teflon based paint that is used on racing sailboats..
