'I'm sure this will be the first of many questions. When I received the fuselage it was already varnished (as were the wings) with a wood varnish. I'm going to remove that varnish around the door openings, window openings around the header above the windshield etc. and replace it with epoxy varnish (polyfiber process). My question is what do I do to the stringers, do they need be stripped/sanded and coated with the epoxy varnish?
Thanks for any help you can provide.

'Again George, defer explicitly to the instructions of Polyfiber and call up their
tech rep for confirmation. I'm betting you'll find out that you need to apply the epoxy
varnish only to parts where other polyfiber things need to be attached to. I think it
is a bit of a one way street, to the extent that you can have polyfiber products touching,
stretched over, rubbing against etc. almost anything without any harm, but it's when
one part needs to be ATTACHED to another that you need compatible
( polyfiber to polyfiber) consistency. Call Polyfiber and ask. I'd further bet that those
parts around the doors and windows for instance only need a bit of sanding, not
removal, a coat of Polyfiber epoxy varnish and you'll be good to go in their direction.

My Fairchild project will have a major investment in covering material, but this time I
will go with a water borne type of and I'm likeing the look of Stewart Systems.

I covered my Christavia in 1998 ( wow...that far back, eh ? ) with Polyfiber and it's
still as good as new. Very good stuff.

'There is a much better product it is called "5 year clear" from Smith and Company Richman Ca. it is a 2 part polyurethane and will stop the UV light from yellowing the wood. I have some in service for about 7 years and it looks like I did it yesterday.

'George,
We covered the stringers with epoxy varnish right over urethane varnish. Didn't seem to hurt it in the least. Holding up just fine, as far as I can tell.
Good luck.
