Curved Body Panels: Verify Paint Gauge Fit Before Comparing Readings
Curvature can affect probe seating and measurement response. A gauge approved on flat reference plates may need application-specific verification.
Updated · NANOLAB Knowledge
Practical approach
Check the probe manufacturer's curvature limits and positioning instructions. Use representative reference conditions where available and keep probe orientation consistent.
A narrow wheel arch and a flat hood can produce different measurement conditions even when painted together.
Decision limits
Do not interpret every difference as evidence of a previous repair. Establish whether the instrument can measure both locations appropriately first.

A paint gauge reading is useful only when the instrument is suitable and functioning as expected. Use its specified verification method before relying on numbers in a correction plan.
Paint Thickness Readings on Steel and Aluminium: Record the Substrate
A thickness record should identify the measured substrate and gauge method. A mixed-material vehicle can produce readings that are not directly comparable.

Measurements near a panel edge may be affected by geometry. An unusual reading needs method verification before it becomes a polishing decision.
