The best way is to cut a plug... same thickness as belly skin. Make it a good fit. Make a backing plate to cover the hole plus enough to rivet to the skin.
C/S all rivets. Rivet the backing plate in place. And then rivet the patch in place.
That is an Air Force approved patch.
Or you could cut a patch to cover the hole plus some room for rivets, taper the edge and rivet it on........ this will cause drag and the other won't.
