Lighting for Paint Correction and Ceramic Coating Inspection
Use complementary lighting and viewing angles to reveal scratches, haze and coating residue without relying on one bright reflection.

Different light reveals different defects
Focused light can reveal fine marks and local residue, while diffuse light helps show overall uniformity and broader haze. A single lamp position may hide defects behind a reflection. Move your viewing angle and inspect curves, edges and darker areas deliberately.
Lighting should support the intended finish. Matte surfaces require assessment of even sheen, while glossy paint benefits from checking reflection clarity.
Set up before application
Arrange lights so the installer can see the working section and inspect it without unnecessary contact. Avoid placing equipment where it creates hazards or unwanted local heat. Account for changing daylight in a workshop with open doors or windows.
Check a test area after preparation and again after levelling. This helps distinguish pre-existing polishing defects from new coating residue.
Make the final check repeatable
Use a consistent walkaround route and inspect in more than one lighting condition where practical. Photographs should preserve comparable exposure and angles when documenting before and after results. A brighter image is not evidence of better correction. Good lighting makes defects identifiable early, while the coating can still be assessed with the appropriate process.
