If you use Stixit to fasten the fabric , you should not need to Dope the airframe.
I really can't recall how much Nitrate I used on mine . but the two pints should be very close.
What you want to do with the Mitrate is seal the fabric weave before paint or other color coats "FUEL PROOF" as Nitrate is not fuel proof.
I have thinned 50/50 60/40 thinner to seal the weave most times two to three coats are needed and brush in one direction one time for each brush stroke.
Wait a while for the first coat to dry and repeat try not to apply too much dope per coat or it will pool thru the fabric and leave a dimple in the cloth.
I use a 1" Sable mop type brush to apply my dope, Don't go cheap on your brush as it will show in the final finnsh later even if you spray the color coat.
