I'm convinced that a layer of deck cloth (see below from Wick's catalog) will be as light and a better wood seal than any fill and sand method. Tony Bingelis recommends it in one of his books. A layer of deck cloth on the wood fuselage requires very little sanding / finishing before priming and uses very little resin. I used deck cloth over my wing lay up while the KR cloth resin was still wet. It soaked up any excess resin from below needing very little additional resin to wet and leaves a surface nearly ready for priming. If you are old enough to remember how smooth the silk stockings were that women used to wear, you will understand what a fine weave the glass has. If you hate sanding you'll love deck cloth. http://aircraftproducts.wicksaircraft.com/item/all-categories/deck-cloth-1080/1080?plpver=10&categid=100&prodid=1997&origin=keyword ( 50" width, 1.45 oz. per sq. yd. threads per inch: 60 length x 47 width. Commonly used over wood or plywood or last layer of fiberglass lay up giving the surface a fine weave for finishing.) Larry Flesner
