Paint thickness readings and accident damaged cars and what happen.
When buying a used car, checking paint thickness readings can reveal a lot about its past — especially if it’s been in an accident. Factory paint typically measures between 90–130 microns. If a panel shows significantly higher readings (200+), it’s a strong sign the area has been resprayed or filled, often due to accident damage.
Repaired cars aren’t always bad, but hidden structural repairs can affect safety, resale value, and insurance. Some sellers polish over damage without disclosing it, making the car appear perfect — until problems emerge later.
Tools like paint thickness gauges are affordable and easy to use. They help spot inconsistencies that could indicate body filler, multiple repaints, or even poorly repaired crash damage.
If you’re seeing patchy or unusually thick paint, get a professional inspection. It's the best way to avoid buying a car that looks good on the outside but may be hiding serious past damage underneath.
