The front half of this plane was sheeted with 3/32 and from behind the cockpit I used 1/16. I used a squirt bottle of water blended 50/50 with ammonia, then rubber banded the wood and let it take it's own shape. I used medium CA for my sheeting. Before I glued it down I shot it with my squirt bottle again so it bends well for final gluing. There are a number of ways but damp wood and CA work pretty well. If you posted in the scratch builoding forum a lot of guys will have different ways of doing things but this is my old stand by.
