7th January 2013 - Sealing the inside of the left wing

I hate painting! probably because I'm so bad at it but it has to be done. Yesterday and today I gave two coats of Randolph Epoxy Varnish EV-400 to the inside of the left wing. The first coat is thinned about 50% to ensure it soaks into the wood. It is important to keep the surfaces to be glued free of varnish so the top surfaces of the wing ribs and spars were not varnished.
The varnish takes about 7 days to fully set and then is impervious to pretty much everything.
The top surface of the wing is still to be glued on and of course can't be painted when it is in position. It was first rough cut from one of the scarf jointed lengths of 3/32" mahogony ply  then masked off  to match the ribs and spars. The glue will be spread to fill the gaps in the varnish.
Next job is to fit out the internal components in the wing: the remote compass, the pitot, and the wiring for the nav and strobe lights, then it is a case of varnishing the inside of the top surface and gluing it on.
