Light silkspan and jap tissue is a lot lighter than .6 oz Fiberglass. You can also lay down silkspan with white glue thinned with water. I am considering finishing a Kaos. Was planning to use Ultra Cote trying out a new trick of painting the whole thing with thinned white glue to keep the covering from lifting and wrinkling. But I was planning on black and gold to match the HP Gold Cup engine. But I doubt black Ultra Kote is not going to winkle no matter what, so now I am planning to paint the fuse with some black polyurethane I have and using gold Ultra Cote on the wing and for trim. Use the black Ultra Kote for trim on the wing. So I am consdering finishing methods. Been a long time since I have used anything but laquer and dope. Don't really care for polyurethane but I have a quart of black, red, and white.
