Conservation of Alkyd Resin Paint Materials ordered, February 1945

Anew technical order, T, 0.07-1-13, was issued on February 1,1945. It stated that due to the strategic nature of the following alkyd resin paint materials, their use was to be kept to a minimum and restricted to aircraft, and aircraft accessories and parts. The list which followed included the aircraft camouflage enamels, gloss enamels, heat resisting enamels, zinc chromate primers, glyceryl phthalate varnishes, and all aircraft lacquers.

These materials were required for use on aircraft and aircraft parts and were not to be used on equipment, vehicles and buildings. Large stocks of these materials were not to be accumulated at any supply or maintenance activity. Lacquer could be applied over old lacquer with no zinc chromate primer as long as the surfaces were properly cleaned.

Spec. 98-24113-B revised to add new requirements for the interior finish of all aircraft, April 1945.

Amendment No. 2 to spec. 98-24113-B was issued on April 6,1945, and added three new paragraphs containing new requirements for the interior finishes of all AAF aircraft. They read as follows (paraphrased to shorten the official verbiage):
