Any idea of what the weight penalty would be in dope and fabric vs. reduced
drag? And is this method more or less expensive than pinked tape?

Just wondering,

Shellac dope would have added 76 lbs. to the weight of a Wright 1902 glider,
and almost 155lbs. to the 1903 "Flyer." ...Based on tests made with my 1899
