Paint repair with 3M Finesse-it
Automotive Manufacturing: End of Line & Offline Repair

Automotive Manufacturing: End of Line & Offline Repair

  • Some jobs are too big or time-consuming to be done on the assembly line. Large area paint repair requires defects be removed, the surface prepared and may require surfaces to be masked before paint is applied and finished. 3M has efficiency tools, supplies and processes for every stage of a repair – allowing you to deliver a fix in the shortest possible time with minimal waste.

Typical Process Steps

  • Tools for offline repair
  • 1. Surface Prep

    Typically, in an offline repair, surfaces are sanded to smooth defects and cleaned to ensure optimal adhesion

    2. Large Area surface repair

    The surface is then masked and primers, basecoats and clearcoats are applied

    3. Paint Finishing

    Then compounding, polishing and buffing takes place to enhance paint quality and factory finish.
