I-CAR · May 7, 2019 · General Motors, Chevrolet, GMC, Buick, Cadillac
Summary
This General Motors position statement outlines strict limitations for repairing bumper covers on vehicles equipped with ADAS sensors. It prohibits any repairs requiring substrate repair materials or reinforcement tapes, and limits the total paint mil thickness to a maximum of 13 mils.
What to do on the job
Avoid any bumper repairs requiring substrate repair materials or reinforcement tapes, and ensure total paint thickness does not exceed 13 mils on ADAS-equipped bumper covers.
How to use it
Use this document to justify replacing a damaged bumper cover instead of repairing it if the damage requires plastic fillers, structural adhesives, or reinforcement tapes. It can also be used to support the cost of paint mil thickness testing to ensure the refinish does not exceed the 13-mil limit.
