Tont B is describing the right way to fill a hole in fiberglass. It's in the books if you want more detail. Something about a "secondary bond".

The easy way is to leave the thruhull in place and cap it off on the inside. There are a couple different ways to do this, depending on whether the truhull is threaded or barbed.
