Just WHY do you say so, Mr P005??
I have had the spars in my top wings inspected recently, as part of a '15 year inspection plan', including the use of a borescope to inspect the holes drilled thru for the 'slats' activation rods, and they look like brand new still!
The spars were painted with a two pack marine standard varnish on original installation, in Dec 1998, and they are certified by my LAME 'as good as new still'.
Those 'rotten' vertical interplane wooden struts are made from the finest spruce money can buy - don't ask how I know that - and I keep them sanded and varnished with the same two pack marine stuff.
They may LOOK a bit 'untidy' in between coatings due to weather affected 'flaky' varnish, but once that is sanded off and inspected, you might be suprised.....
And, yes, mine does carry members of the public....a bit more often this Summer I hope...
Cheerrsss
