I really don't like bondo for through holes. But it does work and lots
of folks use it with good results. The type with fiberglass mixed in
works pretty good for through holes. I still like the metal solution
best because I like metal.

I use to take fiberglass mat and pull fibers, small pieces out of it.
Small scrap pieces work really well. Then mix them in with the resin to
patch stuff like that. It kind of makes a snot ball that can be
manipulated, formed pretty well.
