Ian:

I enjoy your posts and appreciate the info and ideas. I've been a proponent for the use of silicone sealant as a gasket substitute in flush hatches, but it's really the idea that's important. So it sounds as if urethane would be a better mat'l?

So:

How is it applied? at home? with a caulk gun? from hardware stores?(maybe I should look more closely)

Is it soft or hard, elastic, sounds as if fairly durable

Is there a release for it? ie plastic wrap or vaseline for silicone?
