Nicely documented project. I hope you don't get "arithmetic fatigue"
adding up all the hours.

Please advise the weight of the fuselage before you started verses that
when you finished. Also the moment arm balance for the rudder, before
and after. Be kind to the next owner and make sure it is fully
documented in the log books. This is always the "unknown" when looking
at a refinished glider.

is refinishing a glider considered 'preventative maintenance'?
