Military paintjobs matte for airshow also?
Matte paint creates drag and reduces the top speed. The sheen of the paint is often adjusted to suit operational conditions. For example during WWII an aircraft being prepared for a special high-speed mission, such as a dangerous reconnaissance flight, might have its matte camouflage waxed over to give it that edge of speed. Many combat jets have routinely been finished in a semi-gloss, as a compromise between the two. Special schemes for airshows do tend to be high gloss.
