Poly won’t make a good bond (it will fail after a few years) vinyl works a little bit better but epoxy is the only thing you should be using when adding onto cured resin, no matter the composition. Use a thickener like coloidial silica for strength, build and less sag. Other additives have different characteristic, if in doubt buy west systems and use their system to determine what you need. It is pricey but fairly cool proof. Also recommend using a catalyst without blush to avoid the washing between coats or applying finish.

Ok, so say you have a hole on the port side (exposing woven fabric and about a 2 inch hole down into the aft storage) where a cleat was ripped right off the boat!

In this situation, Epoxy or Poly? GO!
