Last fall I drilled several small holes, about 1/4 inch, into the
hollow, sacrificial keels of my cat. I was exploring for water
which has been known to get into the keels, but found none.
Now I have to patch the holes.
Drill the holes to a common size that will be the same size as a pilot
drill for a coarse thread sheet metal screw or a lag bolt. 3/16"
pilot, #14 screw, 1/4" pilot, 5/16" lag bolt, 5/16" pilot, 3/8" lag
bolt, etc.
Screw the above into, then back out of the hole using the bolt like a
tap to create a threaded surface in the glass hole.
Blow out dust in hole or clean threads with acetone.
Mix up some epoxy resin and slow hardener thickened with
micro-balloons to the consistency of glazer's putty, then plug
threaded holes proud.
Let cure 2-3 days, then sand flush and paint to match.
Have fun.

Thanks. I was wondering how to create a surface that mechanically hold
the patch - the threading would seem to do the trick! Actually, I think
my tap & die set has large enough tap to work. I'll have to see if the
glass is thick enough for a coarse thread.
