Fiberglass resin?

[champion221elite]

Im not sure if this is the right place, so feel free to move as necessary.

I need to patch up two holes below the waterline on my Blackjack 29. I had installed two autobailers and they caused more problems than they solved. Now I have two holes tbat need to be patched.

I have the fiberglass cloth, but need some direction of what resin to use. After the area is glassed, I plan on using MarineTex on the hull exterior to fill in the dimples and will sand everything flat.

Once thats done, I have plans to repaint the entire boat.

I am not familiar with Marine Tex, but not all Epoxy(s) are meant for surface finish work. For instance: The 30 minute Epoxy made by Pacer ( Z-Poxy) is difficult to sand flat without over sanding the surrounding area. It is a very strong epoxy for repairs, however.
Z-Poxy's FINISHING Epoxy , on the other hand, is just made for your purpose. Easy to sand even without the need to use too much elbow grease and therefore minimum chance to over sand the surrounding area.

You can tilt the hull so the epoxy fills the void, and use duct tape over the hole. Tape the hole and if its less than 3/4" of an inch you will have a perfectly filled hole after it sets. No sanding to the outside required. I have done this quite a few times make sure to back the area with a few pieces of FG cloth afterwards.

I have 15 minute mid cure epoxy here at the house. If I use the tape method, do I still need to use the fiberglass cloth, or will the epoxy alone be sufficient to fill the hole?

BTW, the holes are approximately 1/2" diameter.

Cloth overlapping the hole, 2 pieces.

I would use the tape method and allow this to fill the hole, but definitely use 2 pieces of FG cloth to back it on the inside. FG cloth adds a lot of strength epoxy alone doesn't add much. the idea is to just plug the hole and create strength from the inside
