Do you plan on painting your models in the future, or is this just a one shot thing. If you do plan on painting a number of aircraft over the next couple of years, and if you have access to an Aircraft Supply at a small general avation airport, pick up a gallon of But. clear dope, and TWO gallons of But. thinner. Transfer the clear dope into 4 one quart cans (from a paint supply store) and you will be set for clear dope and thinner for quite a while and at a LOT LOWER COST than from a hobby shop.
