I have two questions. Can I fiberglass in rainy 60 degree weather? I am working under a closed in porch surrounded by plastic. I am worried that the fiberglass will absorb too much moisture. Any help will be appreciated. Also I have no idea what to do about the portholes. I am probably going to order rubber hatches because I want the sections to be water tight. I don't know what to order and I don't know how to attach them. I do not understand the explanation Nick Shade gives so someone please help.

Thanks

Amanda
