On the whole surface I applied a mix of epoxy and microballoons, to fill all the small gaps.
Immediately I placed 80g fiberglass and again saturate it with epoxy, then removed the excess of epoxy with small plastic plate.

I sticked together both halves, to see how they fit together, and started making some ribs for wings. :)

Same as on the outside, I first fill the gaps with microballoon and then saturate fiberglass with epoxy.
