The air gets hot, then the metal gets hot, then finally the coating cures. It’s a long, indirect trip. It wastes a ton of energy, and more than that, it often leaves the bottom of the coating under-cured. We do things differently. We use shortwave infrared (SWIR) radiators to just&hellip; skip the air entirely.</p>
