I have been asked many times about the longevity of a wooden aircraft.   When properly constructed, sealed and finished, a wood aircraft is as durable as a metal aircraft.  The information in this article was provided to me by the Canadian Owners and Pilots Association (COPA)and is part of the COPA Guide to Amateur-Builts.

Remember that this information is 20 years old and glues have improved considerably since then but the techniques for testing a wooden structure is applicable today.

There is always a great deal of discussion about the "best" way to finish an aircraft and also what is the most economical method for finishing.   While digging through some of the old files at Fisher I ran across a description of how Fisher Flying Products (when it was located in Edgeley, ND) finished their aircraft.  I thought I would share it with everyone as an alternative to using traditional painting methods.
