Summary
This article highlights that vehicle manufacturers have specific, varying guidelines regarding the refinishing of park assist sensors. While some OEMs allow refinishing under strict paint thickness limits, others prohibit painting over minor finish damage entirely to prevent system malfunction.
What to do on the job
Always consult and follow the specific OEM service manual or bulletin guidelines for the vehicle's make before attempting to paint or refinish any park assist sensor.
How to use it
Use this document to justify the research time required to look up OEM-specific sensor painting guidelines. If an insurer questions why a sensor must be replaced instead of refinished, or why a specific paint thickness measurement process is required, use this article and the referenced OEM-specific links to prove that excessive paint thickness directly compromises ADAS safety systems.
