My flying partner and humble self were building and flying at a furious pace. We had planes in the living rooms, bedrooms, and kitchens in both our cottages.
Our wives were also building, finishing, and flying.
Planes unpainted (clear doped, some sanding sealered, in the midst of sanding, filling, sanding again) were hanging in the 'wings'...we were at a standstill!
Doug brought home some 4 oz bottles of CyA, fast drying. An old nylon stocking, folded several times was used to rub the CyA into the balsa, a 4" square patch at a time. Whole sheeted wings, fuse, everything balsa. Then sanded, with 400 then 600.
Primer next, 2 coats, sanded each one. Then 'new' Aero Gloss, then rub out the next day, white compound.
Fast as it dried, no waiting 2, 3 days. It looked like hand rubbed lacquer.
