first only use epoxy, once the polyester in the hull cures the patch is only a mechanical glue joint and epoxy is many times stronger than polyester in that respect.

also you dont add cloth and add larger pieces, you largest piece should be the first one put on, it gives the largest contact to the largest piece. if you start small the largest piece is only glued to a smaller piece.

to saturate the cloth, mix the resin. then put down some plastic, put down the first layer of glass pour on some resin spread it around with a squeegee. add another layer of glass and do the same. you dont want to dip the glass in resin it adds too much resin to the glass, the best hulls have something like 30 % resin by weight, the best you can really hope for by hand is 50% resin.
