When refinishing a pinchweld, at what point should a body shop stop?

• A. Base coat application
• B. Clear coat application
• C. Primer coat
• D. Top coat application

Answer: (C)

In the context of refinishing a pinchweld, stopping at the primer coat stage is crucial because the primer serves as the essential foundation for any subsequent refinishing processes. The primer adheres to the surface of the pinchweld and promotes good bonding for paint layers that follow. It also provides corrosion resistance, ensuring that the exposed metal is protected before any color or clear layers are applied. Before reaching the base coat, clear coat, or top coat stages, the primer must be allowed to cure adequately. Applying additional coatings over the primer without allowing it to fully cure can lead to poor adhesion, bubbling, or peeling later on, which compromises the integrity and appearance of the refinished pinchweld. Therefore, at this stage, the refinishing process can be deemed complete for the pinchweld area, as it’s effectively prepared for both structural integrity and performance.
