I'm psyched up to varnish my wing ribs, but when?
p.36 says to sand and varnish all (right after false ribs install)
p.40 says to varnish inside of ribs 1 and 3 before installing the tanks
p.74 says to varnish them all after installing the flaperon brackets
That's 6 coats
I'm inclined to do the flap brackets, varnish all the ribs, then glue in the tanks last (none of the above)
