Is a paint thickness gauge reading over 400 serious for bodywork?
2 Answers
Paint thickness gauge reading over 400 is serious for bodywork. Here is an introduction about car floor mats: Introduction to car floor mats: Car floor mats are an environmentally friendly automotive interior component that integrates five main functions: water absorption, dust absorption, stain removal, sound insulation, and protection of the main carpet. Functions of car floor mats: The thick base material can block chassis noise and tire noise, and can also completely absorb residual noise and in-car audio echoes, protecting hearing from damage.
The paint thickness gauge measured over 400 microns, which looks quite serious to me as a car owner. New cars' original paint is usually only 100 to 150 microns thick. Such a high value indicates that the body panels have been repainted or repaired, very likely a sign of an accident vehicle. Excessively thick paint is prone to cracking or peeling, and water accumulation during rainy days accelerates rusting. Worse yet, improper body panel repairs can weaken the vehicle's structure, increasing collision risks while driving. I think it's best to promptly visit a 4S dealership for a thorough inspection to check for frame deformation—only cars without major body repairs are truly safe. Additionally, resale value as a used car will drop significantly, and repair costs can be substantial. From experience, regularly measuring paint thickness is key to vehicle maintenance—don't wait until problems arise to take action.
