Thru-Hull Repair

I have a couple of thru-hull fittings that I am looking at removing and I want to seal the hull back. What is suggested to use for the filler of thickness of the hull?

I'd use glass cloth. Bevel the opening somewhat. Overlap the glass inside and out. If you ever bump something you can be sure it will be exactly on that old hole...

Get the West Systems 'Fiberglass Boat Repair & Mantenance' manual #002-550. It's available online online at: WEST SYSTEM | Use Guides It covers how to patch holes in boats. You want to do this repair right as a patch failure would be embarassing. You'll need to grind the hull back quite a ways and taper into the puka, then relaminate back to the thickness of the hull and grind smooth.
