Look under a magnifying glass to see if 100% of the fibers are impregnated after your one coat. If so, you should be OK. I was not after one coat. Then I added a second coat. Now 100% of the fibers were under resin. You do not want to sand and be able to cut cloth fibers. I sanded. Primer to follow.

I glassed my wings some time back using a nice rubber squeegie I got from a boat/canoe supplies shop and stopped after one thorough fill coat - then light wet sanded and set aside for a later set of primer coats. Did I mess up??

IMHO, you haven't screwed up, provided the weave of the cloth was saturated. This doesn't mean that the mesh of the weave will be filled to the top with resin. A light weight filler can be used to fill the weave. I suspect that the recommendation for additional filling with resin is to allow the wood to remain unpainted, like in a boat. On the other hand, given the fine weave of the lightweight cloth, I suspect that the weight of the second coat of resin would be insignificantly higher than resin plus a filler. For what it's worth.

Basicly he said it just for show and not for go. When I did mine, if I sanded thru the glass I just added another coat of resin. I used West Systems Epoxy. The wings were painted with Systems Three paint applied with a roller. Though they don't look anything like Clements, they don't look to bad either. The System Three paint was very easy to work with and since it is sort of a rubbery paint its been on my wings, sitting in stroage for five years, with no cracks. Only a sight yellowing.
