There is no paint that I know of that is water proof, not AwlGrip not AlexSeal, not Imron, not Bilgekote. Interprotect 2000 is as close to waterproof as you can get and it bonds to the substrate at nearly 2000 PSI.
Even Interlux will tell you BilgeKote is NOT waterproof. If you live in a warm climate where it never freezes you might avoid lifting and peeling for a period of time but in the Northeast or colder climes when the paint is permeated by moisture and the moisture behind it freezes it expands and separates the paint from the fiberglass. Ask me how I know..?
For me it's gelcoat or Interprotect in wet areas of the bilge..
