So, my plan, is to take off the hardware and inspect the holes. Then I will use the bent nail drill bit technique to remove some core as needed, and vacuum out. Then I will tape the holes from behind with duct tape, and inject using a syringe West Systems 105 epoxy with hardener and fill the holes. I understand that I have to squirt it in a few times, as the balsa absorbs quite a bit. Any idea of the timing of that? Do I squirt, wait a few minutes and squirt again? Or do I squirt, wait a few hours and mix a new batch? Once done, I'm supposed to then mix a fresh batch with the colloidal silica as paste and inject for a final fill. Does this seem like a good plan? Then, when cured in a day or two I will redrill the holes, and use 3M 4200 to bed the fittings. Still just a little confused about the timing of the epoxy.

I'll see what it looks like when I get the stuff off. It may be very easy to do just that.

Not sure what you meant by "won't epoxy the ones that aren't leaking." Does that mean you are only going to drill out; epoxy fill; and, redrill just the holes that had leaks?? I'd do all 18. ----- Original Message ----- From: Daniel Rich To: For and about Montgomery Sailboats Sent: Monday, February 21, 2011 4:05 PM Subject: Re: M_Boats: Rebedding deck hardware
On my way to west marine now. Looks like 18 bolts have got to be done. One life line rail, bow pulpit, and 1 cleat. Only 3 leaks, but gotta pull those parts. Won't epoxy the ones that aren't leaking.

daniel:
below are my person 'definitions and uses' with the products discussed -
5200 - below waterline applications. use for fittings you will _never_ (essentially) remove. 5200 is excellent and 'permenant' adhesive and sealant. 4200 - above waterline applications. a challenge to remove but can be done (carefully so as not to damage the surface ... ie the gelcoat) 4200 is an a sealant and a good adhesive. Life Calk - above waterline applications. not difficult to remove but you must re-bed your hardware more often than with 4200. life calk is a sealant and a weak adhesive.
