Fiberglass question

[Joker2]

I am glassing up my new transom with 17oz. bidirectional cloth (pretty thick), I put the first layer on and spread out the resin, after rolling out all the air ( or so I thought ) there were a couple of small areas that remained a little white in color. After it dried I tapped on those areas and I could tell that the resin did not soak through. I have already done the outside of the transom and it came out nice, I guess I was rushing or somthing that day. My question is what is the best way to correct it so I can continue with more coats of resin?
