Once you cover one side of the Koverall applied, you just brush Stix-it on the edge of the Koverall where you will have an overlap, ususally 1/4 to 1/2 inch. Just like plastic covering, you plan so the seams are the least visible (i.e. cover the bottom of the wing first).

Nitrate is fine to appy Koverall, I just think the Stix-it is easier to apply on curves. The nitrate just does not dry fast enough to hold the curves. The Stix-it is instant stick once heat is applied. Once you go over the Koverall with the first coat of nitrate to fill the weave, you will further stick the Koverall to all areas of the frame.
