3M large area clearcoat repair 사용자 설명서

This application provides a system that allows AOEM’s and their suppliers the opportunity to repair large defects within the

clearcoat layer of the paint system. A large defect could be defined as an area equivalent to approximately 1-2 square feet.

The types of defects that are typical of this area are orange peel, overspray and blend lines.  

Tech Tip: Due to the variety of layering systems present within the automotive marketplace, abrasive selection within all

steps of these systems may vary slightly depending on the particular technology present within the account.
