The formulation is packaged by adding 8 oz of this solution and 20 ml isobutane propellant to a 12-oz K50Q6 lined, seamed car. A Newman-Green B-14-50 rust-resistant valve and B-14-3 sprayhead, with a 0.027-in. internal metering orifice, make up the spray assembly. (This particular sprayhead can be removed from the can, when necessary, for rinsing with water.) For best results, shake the can before using, spray the fabric lightly, and iron dry. Repeat this process, if necessary, until the desired stiffness is obtained.
