Rust or Paint Blistering Around Chrome Liftgate Applique (Refinish Liftgate/Apply Two-Way Tape)

Some customers may comment that bubbles are forming under the paint or rust stains are forming around the chrome liftgate applique.

This condition may be caused by insufficient isolation of the chrome applique from the painted liftgate, resulting in deterioration of the painted surface.

1. Remove the liftgate trim panel, the outside liftgate handle, the chrome applique and the emblems following the procedures in SI.
2. Refinish the liftgate.
