It happens because aluminum is porous. It traps air and moisture inside the metal. When you crank up the heat too fast, those trapped gases panic. They expand and fight their way out, punching right through your curing powder on their way to the surface. We handle this with high-density shortwave infrared (IR) lamps. It&rsquo;s all about how you control that heat.</p>
