The covering system is Ceconite (Like Coverite without the adhesive backing)and Randolph dope. The outer edges of the wood frame has an adhesive brushed on. The adhesive is a liquid form of the Coverite backing. There are several products on the market for model builders (SIG stix-it and Coverite brushable).
Then the fabric is attached with a sealing iron. This covering is super light (due to the no adhesive back and very shrinkable.
This is one of the same processes used on full scale aircraft. Once you tighten the fabric(with a heat gun) then a 50/50 dope and thinner is applied to seal it. "Rings like a drum" Light primer and paint next...
"Miss Champion" For now...
