Is a paint thickness of over 200 normal?
3 Answers
A paint thickness of over 200 is not normal. Below are specific details about paint thickness: 1. The original factory car paint should not exceed 180 microns. For repainted areas, the thickness should not be below 120 microns. 2. Car paint consists of four layers: the electrocoat layer, the primer layer, the basecoat layer, and the clearcoat layer. The electrocoat layer provides rust protection for the car body; the basecoat layer gives the car its color; the primer layer acts as a barrier against UV rays, protecting the basecoat layer; and the clearcoat layer is the outermost layer of paint, functioning like a phone's tempered glass screen protector to safeguard the entire paint job. Its hardness index is a key factor in determining the paint's resistance to wear.
I usually take care of my car myself and have some experience with paint thickness. Generally, a new car's factory paint thickness is normal around 100 to 150 microns, while over 200 is a bit thick but not a big deal. I've seen some high-end models or cars with good painting processes where the factory paint is slightly thicker, providing extra protection, such as against scratches or rust. However, if your car has over 200 microns, you should first check if it has been repainted, as repainting often adds thickness, especially if done poorly, which can lead to paint cracking or fading. I recommend buying a small thickness gauge for just a few bucks to measure it. Regular washing and waxing can also extend the paint's lifespan—don't let thick paint become a burden affecting aesthetics. Overall, as long as the thickness is even and free of bubbles or sand marks, you can rest easy.
As someone who's been busy in the workshop year-round, I've handled thousands of vehicles. A paint thickness of over 200 microns is indeed on the high side, as the standard factory thickness typically ranges between 100 to 150 microns. Exceeding this value might indicate special factory coating or subsequent touch-up painting. Uncontrolled layering during touch-ups can build up the thickness, but thicker paint isn't always a bad thing—it can enhance corrosion resistance, which is particularly useful in sandy or dusty areas. However, thick paint might conceal defects like old scratches or rust spots, and excessive paint can even add unnecessary weight to the body. I always remind car owners to check for uniformity, using professional tools to measure multiple spots to avoid misjudgment. If large areas of thick paint are found, it's best to visit a reputable repair shop for diagnosis to prevent minor issues from escalating.
