Fiberglass question

[Joker2]

I am using west system epoxy 105/205, yes I sanded the pre resined wood and then wiped with lacquer thinner, then wet out some resin, then added the cloth (backed with 3/4 oz. mat) then put more resin, I did other areas on the transom which came out good, think I just didn't work it in enough in these spots, tried sanding one of them down pretty far ( almost through to wood then resined the spot and it did go through to the wood, also cut out one, and I will add a patch, this will create more coats of resin to level things out, not sure if I want to do that all around. Not sure what the best way to go is?
