Application of handheld UV inspection lamps in non-destructive testing of vehicle body coatings and used car appraisal

In high-end car detailing, original factory paint repair, and used car accessory inspection, it is difficult to identify "secondary paint touch-ups" or coating defects after fine polishing with the naked eye. Many large car dealerships have introduced high-purity handheld UV lamps for non-destructive screening of vehicle body coatings upon arrival.

Different compositions and batches of automotive paint exhibit varying fluorescence reactions under ultraviolet light excitation. Original factory paint and repair paint (or putty layer) will show significant color differences or shadows under UV light of a specific wavelength, thus enabling non-destructive testing.
