Basic SAPL – the app interprets results for you
The Paint Coating Analysis System (SAPL) is an algorithm built into the NexPTG app that automatically translates raw µm values into plain language.
Indicates an undersized paint layer, which may signal insufficient protective coverage.
Typically 0-69 µm
Thickness is within normal limits for this vehicle type and panel, indicating factory paint thickness.
Typically 70-165 µm
A localized variation from standard. Suggests a minor touch-up, paint point repair, or small refinish.
Typically 166-300 µm
Suggests that the area was filled in the past and the vehicle underwent body repair work.
Typically 301-500 µm
Indicates bodywork intervention and post-collision repair on the panel.
Typically 501-700 µm
Points to major structural body repair and typically indicates severe collision history.
Typically 700+ µm
