RE: Sig Koverall-substitute?
For the past 25 years, all of my planes have been covered with a dacron fabric of one sort or another. I started out 25 years ago selling and using Ceconite. Later on I used Stitts fabric, and found it to be exactly like Ceconite. I couldn't tell the difference. Since I owned a model shop, I also tried SIG Koverall, and ditto - it's just like the others. Now, however, I have discovered a real bargain - from Aircraft Spruce and Specialties - they sell a non-certified dacron fabric that is identical to all of the above, 1.8 oz./sq.yd., and for less than $4.00/linear yard, that is 66" wide.
I apply with thickened nitrate dope, then shrink, then apply three coats of nitrate dope thinned 50/50, and paint with latex house paint, brushed on. Apply all trim, and then wax with Bissell furniture spray polish for a nice sheen.
Once upon a time, way back, I covered a plane with painted Coverite. That's when it first came on the market. I swore - never again, for after a year it looked awful. Ceconite/dope and latex paint will last forever. Take my word for it,
