Ceramic Coating Patchiness After a Partial Repaint
A repaired panel may have a different paint and preparation history from the rest of the vehicle. Treat that difference as part of the diagnosis.
Updated · NANOLAB Knowledge
Practical approach
Obtain the refinishing information, coating history and timing. Have the refinisher and coating installer resolve compatibility questions.
A replaced door cannot automatically be assumed to carry the same coating system as the untouched panels.
Decision limits
Do not apply a maintenance product to conceal an unresolved paint or preparation issue.
