I spoke with the originator of this thread last night along with a couple of other folks for over an hour. Again, I do not divulge who they are, location or any contact information to anyone plus the information is discarded when I end the conversation except for a follow up.
He was advised the original material was marine putty, clean it out with a dremel, sand the fiberglass lips and suggested using Water Tite. I have used that material for many years and yes it has proven to work and never crack again. It is a slow cure and may need several applications. All said and done, the cheapest white paint is white Krylon spray pain for plastics which I advised the owner to cover the boat so not to overspray.
The owner has my contact information for future reference which I asked him not to divulge as I give that out on an individual basis.
