CAUSE
Insufficient protective coating of the aluminum door trim causes oxidation to form and trail down the door
skin.

paint. Paint correction may be required if the streaks cannot be removed from the vehicle clearcoat.
PROCEDURE
1. Replace the shaft cover (window molding) on the affected door following ISTA repair instructions for the
applicable model and trim being replaced. A photo is shown below demonstrating which trim is to be
replaced. A driver’s door shaft cover is being shown as an example, but any of the 4 doors can be affected.

invoiced on the RO and claimed in conjunction with this sublet repair) on the repair order at the actual cost
charged with no handling or markup. The sublet amount must also include any discounts or allowances.
The appropriate charge for the necessary repair-related paint work procedures is determined by comparing
the charged amount against the corresponding amount that is based on your warranty rates.

for price comparison purposes.
It is your center’s responsibility to review the repair cost estimate prior to the repair being
performed. This will help ensure that the amount requested for the paint work is customary, fair,
and reasonable. Also, it must not exceed the scope of the repair work described in this bulletin.
