#### SUBJECT: ROOF DITCH MOULDING COMES LOOSE FROM VEHICLE (REMOVE, CLEAN AND APPLY ADHESIVE)

#### VEHICLES AFFECTED: 1992 "B" BUICK ROADMASTER SEDAN

#### Condition:

----------- Ditch moulding coming loose from vehicle.

#### Cause:

------ Inadequate adhesion

#### Correction:

----------- Perform the following procedure:

1. Open rear door and remove ditch moulding retaining screw.

2. Remove moulding by slowly pulling upward.

3. Thoroughly clean adhesive (butyl) from moulding and ditch area using adhesive remover such as 3M 08984 or equivalent and allow the cleaner to flash off.

#### IMPORTANT: The new adhesive does not bond well to butyl. Removing as much butyl as possible will provide the best retention.

4. Apply a 1/4" bead of 3M ULTRAPRO AUTO BODY SEALANT (CLEAR) #08302 or equivalent inside the ditch.

5. Reinstall the moulding on the vehicle by positioning the rearward end under the back glass lace moulding, pushing the moulding into the ditch and installing the retaining screw.

6. Wipe off any excess adhesive (squeeze-out) from the moulding area.

7. Secure the moulding on the vehicle using an appropriate tape until the adhesive cures.

8. Repeat for other side of vehicle.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
