I-CAR · August 1, 2024 · BMW, Nissan, Infiniti
Summary
This article establishes that dirt nib inclusion is an unavoidable reality of the refinishing process, even when following strict cleanliness protocols and industry best practices. It highlights that both major paint manufacturers and OEMs (such as BMW, Nissan, and Infiniti) acknowledge that minor imperfections occur and require de-nibbing and polishing to achieve a quality finish.
What to do on the job
Perform de-nibbing and polishing as a standard post-refinish quality control step to remove inevitable minor paint imperfections, referencing paint maker and OEM guidelines to justify the process.
How to use it
Use this document to defend the necessity of 'de-nib and polish' operations on estimates and supplements. When insurers claim that a clean paint booth should eliminate the need for polishing, reference the quoted statements from BMW, Nissan, Infiniti, PPG, and BASF to prove that even factory 'clean-room' environments and paint manufacturers recognize dirt inclusions as unavoidable and require post-repair polishing.
