I`ve sprayed a lot of boats with AwlGrip over the past 30 or so years, and always got good results. A few weeks ago I rolled a 27` sailboat hull with AwlGrip. First time I used that method. It looked as good as a spray job, but took longer. I prefer spraying. AwlGrip will hold up as long as gel coat, at least 15 years if not abused. To say a gelcoat job will hold up for 30-40 years and still look good is ridiculous. Maybe if it was stored in a barn for most of its life, However, gelcoat can be rejuvenated when it dulls out over the years, but the spider cracks are still there. not so with Awlgrip, but AwlGrip retains its shine longer. Gelcoat tends to spider crack faster than AwlGrip.

Here is another approach.
I just finished spraying an antique (1959) fiberglass 14` runabout with automotive enamel. Used a single stage acrylic enamel with reducer and hardener. It shines as well as Awlgrip. Should last 10 years or so. How long does the finish on your car last? I wouldn`t use it on a boat kept in salt water all year. The cost was $26 a quart, + the reducer and hardener. It is a 8-1-1 mix. That means for 16oz of paint you use 2 oz. of reducer and 2 oz. of hardener, so a pint of reducer and hardener go along way.
Buy it at your local Automotive Paint dealer I used PPG brand. They have factory stores. So does Dupont. Finishmaster Automotive and Industrial Paint stores (Dupont dealer) will carry AwlGrip at much cheaper prices than any marine related supplier. Check them out on the Internet, probably a store near you.
