Now, on the surface, it looks like we&rsquo;re just trying to move planes through the hangar faster. But it&rsquo;s deeper than that. The way IR heat hits the paint actually changes how the plane handles a bird strike or a spray of gravel at 500 mph.</p> <h2 id="getting-the-chemistry-right">Getting the chemistry right</h2> <p>Think about a standard convection oven. It heats the air, then the surface, and then the heat slowly creeps inward. It&rsquo;s a slog. IR lamps are different. They send electromagnetic radiation straight through the coating. It hits the bottom and the top at the same time, triggering the curing process everywhere at once. When the coating cures evenly from the metal skin all the way to the surface, it doesn&rsquo;t get as brittle. That&rsquo;s the key. A brittle finish just snaps under the pressure of an impact. But an IR-cured finish has enough &ldquo;give&rdquo; to soak up that energy and stay intact.</p>
