Fiberglass guys need you input

[scotty77]

Redoing a old chris-craft boat. Need to fill in the exhaust ports. Looks like about 3/4 inch wood then 3/8 inch fiberglass. Here is what i was thinking tell me what you think. Cut a round piece of 3/4 inch plywood just a little smaller that the hole that is there. Then use some west system thickend epoxy ( says is very good for bonding wood together). Glue new peice of wood into the hole. Then bevel the the area around the the repair out a inch or so. Then use west system resin and mat to make flat. Then some evercoat 870 for filler work. That sound like a good repair?

Thanks

I believe you should bevel the hole so that the outer diameter of the bevel is about 1.5 inches larger than the hole, then make a beveled round plug of plywood, trim and grind until it fits snugly. This will ensure a good bonding surface area for the epoxy and a strong repair that will be less likely to ghost. The rest of your plan is fine.
