I use Nitrate dope on most of my planes. I use it over balsa and silkspan and polyester fabric. It is easy to do and is forgiving to install. You can go back and fix errors as you work with it much easier than you can with plastic film coverings. Is it as quick as plastic?....NO but easier in my opinion. Not 'one step' as with iron on coverings but many steps. I install silkspan or polyester fabric the same way: Two coats of thinned dope 50%-50% on the frame and lay water soaked fabric on the frame and smooth out as much as possible. Then using dope thinner or laquer thinner on a brush wet the perimeter of the section being covered through the fabric and rub down with fingers. It sticks in a minute or less. As fabric dries it shrinks a bit and becomes drum tight. Thinned dope is then brushed or sprayed over the whole area in layers. Then painted with most any kind of paint . Fuel proof paint if needed. This is nice to get textured finishes or a non glossy finish.
