I too have been removing the screws and injecting West System. But I
do not re-drill since I believe this can expose the wood again. Once
the holes stop soaking in the epoxy I re-screw them before it sets up.
Careful taping and clean up are important to not turning this into a
disaster. But it does allow me to do as much as I want at a time. So
far all the leaks have stopped and no new ones have appeared.
Eventually the entire area will be done. BTW, this is only the cockpit
area. The rest of the decks are fiberglass. Another method would be to
epoxy the teak to the deck with screws and fender washer ON TOP of the
teak. Then fill the holes after the epoxy has set and the screws are
removed permanently.
