I kept track of the weight increase as I applied the .73 oz. / sq. yd fiberglass. Always curious of the weight gain of finishes.
The estimate of area excludes the ailerons and flaps and is about 2505 sq. in.
Same procedure on both sides; fiberglass then sand edges, second coat then prime and sand all the primer off.
Spot fill and then make it smooth as a baby's butt!
