RE: Balsa Sheeting Question
Tedmo hit the nail right on the head. How and where the sheeting will go has a lot to do with the thickness of the sheeting. I had one kit that had 3/32" sheeting that had to be wetted to apply on the turtledeck. The wood was hard and when it started drying out I heard a large "POW" behind me. The wood actually split violently as it dried back out. I removed the 3/32" and resheeted with a softer 1/16" sheet with much better results.
Let us know what application you are talking about and it'll be possible to give a better answer.
