Application focus

A closer look at
vehicle paintwork.

Support your inspection with measured coating thickness, rather than appearance alone.

01

Used-vehicle evaluation

Compare readings across metal body panels as part of an overall vehicle assessment.

02

Bodywork & refinishing

Record paint-thickness readings to support discussions about panel condition and refinishing.

03

Inspection records

Use real-time Bluetooth transfer in a compatible data-recording workflow.

Know the boundary. A thickness reading alone does not establish accident history. This gauge is intended for suitable metal substrates, not direct coating measurement on plastic bumpers.
