Dennis,
All the above methods work well and are very east to apply. The method I like best
Apply four coats of Supercoat dope thinned 50/50. Lightly sand the wing to remove high spots and make it smooth. Cut a piece of Koverall leaving at least 1” to pull on to remove any wrinkles.
Starting on the bottom next to the fuselage, place a drop of thin CA glue, wipe off the excess CA glue with an clean cloth rag, then lightly stretching the Kuoverall the width of the wing next to the fuse, place another drop of CA glue and wipe off the excess as before. Working your way down the length of the wing towards the tip, on the leading edge and trailing edge, place additional drops of CA about 1” apart and wipe off the excess CA.
At the wing tip, work slowly and stretch the Koverall and tack in place with drops of CA glue. If needed apply heat to help the Koverall to conform to the wing tip shape. Once you have the Koverall attached, apply more CA to the outside edges and wipe off the excess CA glue. Make sure you cover the top and bottom of the wing before you attempt to shrink the Koverall. This goes pretty fast using the thin CA glue. Using this method only took and hour to cover the wing on a 78” Kadet Senior.
Shrink the Koverall with a heat iron on the medium to low setting. Start on the boron and shrink only two rib bays on the bottom, then two bays on the top, alternating as you work towards the tip. The coving should be tight and smooth, check for any works you may have and remove the warp by twisting and reheating the covering.
Once you have ithe wing coved you can apply the Supercoat dope to the covering (only one coat of Supercoat) dope and allow it to dry over night. The next coats of dope will light coat dope thinned 50/50, when dry lightly sand with 400 wet or day sandpaper (dry). At this point the Koverall look and feel pretty nice with the weave pretty well sealed. If you want you can apply the color dope now, if you want fill the weave of the Koverall apply two more coats of light coat and lightly sand.
My old friend Claud MaCulough and I built two Sig Kobra’s that were finished, one covered in silk and one with Koverall, the same amount of dope and paint, in the end both were the same weight when finished, no engine or or R/C gear were installed yet because they were going use different engines.
One other note, I built a Veco Chief (pollywog) for the Nat’s and VSC, it also was covered with Koverall that was awarded the Spirt of 52 at the Nat’s and the high point Finish for OTS at VSC.
