Never glue wet wood to a framework! What happens is the wood swells when wetted. If you glue it down the wood eventually dries and un- shrinks. The wood will pull in bewtween fromers and you will get an airplane with the classic 'starved horse' look. The best thing to do is custom fit lengths of wood to lay along fuse formers or wet the wood to bend around formers and then just rubber band it it place until it dries. Once the wood is dry remove rubber band for fitting and gluing. Then you will be more apt to fit the wood where you want it to go.
