RE: Sig Koverall
To Calmo2:
For 25 years now I have used nothing but Ceconite to cover my planes - all 1/3 scale or larger. Ceconite is like Koverall - same generation of fabrics - but is certified for full scale useage. I apply using Ceconite "super seam glue", that is thinned 50/50 with laquer thinner. I brush one coat onto the wood - then brush through the fabric while covering. For a wing - I wrap the fabric around the leading edge - only gluing at the trailing edge and ends. This gives a "no seam" leading edge.
After the glue has dried overnight, I shrink using a heat gun - but be careful here - keep the gun moving. A safer way is to shrink with an iron, but when you have covered as many planes as I have, the gun is a whole lot faster. I then apply three coats of nitrate dope, thinned 50/50 with laquer thinner, using a bristle brush (the cheap ones). Then I paint the fabric using latex high gloss exterior paint. I like Behr from Home Depot, and Sherwin - Williams paints best. This is applied with foam brushes - (the good ones with the round handles). Five coats - thinned to cream consistency- brushing each coat in a different direction. When finished - no brush marks are visible.
IMPORTANT: I only fly gasoliine engines - so the paint never gets messed up. Don't know anything about using glo with this type finish.
After the airplane is fully completed, and all decals applied, I spray it with Bissell Furniture polish wax, and rub dry. This gives it a nice gloss. I hate plastic finishes.
