He used silicone in the screw holes and a button type patch for the

Sounds pretty good. When I removed the LORAN antenna from my old 150, I bolted
an aluminum patch over the hole from the inside. I used small aircraft grade
bolts in the existing screw holes. I then sealed it with white silicon -- it
actually matched the paint pretty well. I also smeared silicon between the patch
and the skin before bolting it in. All done as advised by the local A&P.
