Stop the Bubbles: Getting Aluminum Wheels Right with Powder Coating

If you’ve ever powder coated aluminum alloy wheels, you know the nightmare of surface bubbling. It’s frustrating. You spend all that time prepping, only to find these tiny pinholes and bubbles staring back at you. Here’s why it happens: air and solvents get trapped in the coating and try to escape. But if the surface dries too quickly—basically “skinning over”—those gases have nowhere to go. They get stuck, and you end up with a finish that looks like a sponge. To fix this, we use twin-tube IR lamps. It’s all about how we handle the heat.

Dealing with that annoying “skin” in powder coating

Ever pull a part out of the oven and see those tiny pinholes or bubbles? It’s frustrating. Usually, it happens because the surface dried too fast, creating a “skin” that traps gases and solvents inside. It might look okay at first glance, but since the base didn’t bond properly, the whole thing can just peel right off. We found a way to fix this by changing how the heat actually hits the part.
