How Do You Fill-In Unused Through-Hull Holes?
Although most of the reference books detail how to install a new through-hull and seacock, no one mentions how to fill in unused bolt holes when replacing a seacock with a new one -or even the larger hole when eliminating the through-hull alltogether.
How do you safely fill in bolt holes in a fiberglass hull? Just filling with thickened epoxy doesn''t seem strong enough.
Thanks in advance for your advice!
