Can anyone point me to some good on-line info on plugging old through
hull holes in a fiberglass hull?

Any other advice appreciated. The yard wants 6% of what I paid for
the boat just to plug one and put a new backing block in another. I
hate working with glass but it looks like I'll be doing this myself.

Working on fiberglass is a PITA, especially the grinding part. But if
you do good prep work and put up a dust barrier, it's not so bad. I
f'g'ed over two uneeded thru hull holes in our boat, this spring I am
going to do two more.

The round gray spot is not the patch, it's the greenish area below the
gray spot. The gray spot was where some kind of non-functional electric
doo-dad had glued in place against the hull.

One of the nice things about fiberglass is that it's not difficult to
make it even stronger (and lighter, if that's an issue) than original
when making repairs.

I plugged such a hole in about 3 or 4 hours. Grind out a taper
around the hole, put in some wax paper and temporary backing, splat
on a big gob of glass, wax paper and a smooth light piece of plywood
held in place with sticks jammed in the ground and wait an hour.
Sand if needed, and bottom coat.

It's easy, and the price mentioned is for stupid boat suckers.

They ask that much 'cause they sometimes get it.
