Combine this with airless technology (compressed air is only used to spin the cup, not spray the paint) and a low particulate velocity, and you have a drastic increase in transfer rate (the amount of paint from the sprayer that hits the surface) compared to the typical HVLP paint gun used by your local body shop. In addition, the charged particles repel each other in mid air, so they never clump together – creating an ultra fine particulate spray. As the paint droplets bounce off the cup and into the air, they are immediately attracted to the nearest opposite charge, which happens to be the vehicle. Paint is slammed into a bell cup via the spinning bell, igniting a “shearing” force that creates minuscule droplets. That’s right – this bad boy spins up to 70,000 rpm to produce charged droplets that attract themselves to the subject vehicle in the booth. If you’re wondering how these things work, just imagine if the droplets spewing out of your paint gun were electronically attracted to the surface of the car – without the use of compressed air! It also happens to be the most advanced paint application technology in the world. This is what all manufacturers use today to paint a car, and what the majority have been using since the late 90’s. Say Hello to the Electrostatic Rotary Bell Atomizer Every question you’ve ever had about orange peel on the factory finish will be answered here. And while we have a separate article addressing the other factory paint defects you may see on a new car, this article focuses specifically on orange peel, including where it occurs within the automotive paint process.ĭisclosure: This is a very in-depth article, so get comfortable. There is a lot of chemistry involved, and while you don’t have to understand it to the nearest micron, knowing the HOW and the WHY things occur will separate the myths from the facts. Paint is one of the most misunderstood automotive topics out there, and not just to the average consumer – we’ve run into professionals who had a hard time explaining it. Maybe it’s because the science behind it all isn’t clear-cut. The majority of articles, interviews, and forum posts you find online explaining orange peel on a new car is, unsurprisingly, opinionated and false. Maybe instead you assumed that orange peel is most obvious on high-end cars because the paint is “applied by hand”. ![]() You assumed all along that factory paint shops are negligent and that orange peel is a result of their “improper” or “rushed” application process. And guess what? It’s not going away anytime soon. In fact, there are industry standards for orange peel on a scale of 1 to 10, used by every manufacturer. That orange peel on your new car? It’s left there on purpose.
