After following the explicit directions and buying the required materials, I still had a leak in my forward hatch. I do believe I can attribute the failure to the fact it was a Bomar Hatch with on 3/16" lens. The top part of the hatch has two "stringers that offer the actual support of weight on the hatch. I think the thin plastic flexed enough to break the seal. I wonder if it was a factory installed hatch. At any rate, I tried something different. I used Ultra High Bond double Stick tape under the plastic. I set the plastic in place then took a razor knife to trim the margin the extended outside the lens perimeter and caulked that with the Sikaflex material. I shaped the sikaflex so it was convex above the plastic and hatch frame. I also taped so the Sikaflex extended out onto the plastic and the frame. I think it is going to work. The lens is secured much more that the adhesion of the Sikaflex/primer method I used the first time. If I had to do it over again, I would buy a new hatch.
Also, I am going to tell you a crazy method of refinishing my binnacle and hatch frame. About 5 years ago, I bough two cheap winch handles that were powder coated. The powder coating came off immediately. I deoxidized the handles and sprayed them with black Flex Seal. I used those handles mostly every day (sailing charter business) and after 5 years, they still looked good. I stripped my binacle and hatch, deoxidized and primed them (I didn't prime the winch handles) and coated them with black Flex Seal. It looks really good with the crepe finish it had oroginally. I will report if I start seeing a problem. The Flex Seal isn't designed as a finish so you have to spray slowly and far away to get a nice finish without running.
