Why don't you follow the directions that come with the Koverall? They are short, but they answer most of the questions you asked. Apply at least one coat of nitrate dope, although Sig recommends two. You can thin the dope it up to 50% and add talc for filler if you like. Sand smooth, use like 220-240 grit. Then apply the Stix-it, let it dry, and iron on the Koverall. Use just enough heat to get the glue to stick well and no more. Cover the tail parts with two pieces, apply to one side, then trim the edges, then apply the other side, trim, use more stix-it on the seam, let dry, and iron it down. The use the iron and shrink it tight. A little more heat may be needed but be careful, Koverall will shrink a great deal and with a lot of force, it *will* warp the LT-40 tail structures if too much heat is used.

Then use 1-2 coats of nitrate dope to seal it. You can wet or dry sand, and apply more coats depending on how smooth you want the finish. After that, it's up to you how you apply color. If the butyrate is your color, now is the time to apply it.
