Inspecting Ceramic Coating on Metallic and Pearl Paint
Use varied lighting and viewing angles to check metallic and pearl paint for coating residue without confusing effects with defects.
Updated · NANOLAB Knowledge
Metallic and pearl finishes change appearance with the light and viewing angle. That visual complexity can make uneven coating residue harder to detect. Inspection should separate the paint’s intended effect from local smears or missed removal.
Establish the uncoated reference
Inspect clean prepared paint before application. Note existing colour variation, repairs and any remaining polishing marks. A pre-application photograph helps distinguish an earlier difference from something introduced during coating.
Use consistent lighting rather than relying on one bright overhead source. Broad light reveals overall appearance, while a directional source can expose local residue.
Inspect from several positions
After the product’s prescribed removal stage, move the light and viewing position across the panel. Look for patches that stay in a fixed location as the intended metallic effect changes. Check curves, door handles and panel boundaries where wiping may be less consistent.
Do not add more coating simply because the paint appears different from one angle. Confirm whether the issue is residue, preparation or the underlying finish before choosing a correction.
Record and resolve local concerns
If a suspicious area remains, follow the instructions for the installed product and its curing stage. An immediate levelling adjustment and a cured high-spot repair are different processes.
Read coating high spots and final inspection. Use the current NANOLAB product information for application timing, and verify the finish under more than one lighting condition before handover.
