Talcum Powder and nitrate dope for wood sanding sealer
for really light finishes, rub the talc into the wood, then dope with half-and-half dope and thinner. An old Frank Zaic yearbook has a section on hand launch glider wings. Seal the wood, then apply thick calamine lotion. Let dry, sand down, more sealer and dope. I have not tried it.
