Spray-in Bed Liner General Information
Important: Service agents must comply with all International, Federal, State, Provincial, and/or Local laws
applicable to the activities it performs under this bulletin, including but not limited to handling, deploying,
preparing, classifying, packaging, marking, labeling, and shipping dangerous goods. In the event of a
conflict between the procedures set forth in this bulletin and the laws that apply to your dealership, you
must follow those applicable laws.
Important: This technical service bulletin (TSB) can only be completed by certified repair facilities who have met all
specific training, tool and equipment requirements pertaining to the vehicle Brand and Model serviced. Repairs must
be performed by a technician who has successfully completed the required training.
A spray-in bed liner (RPO CGN, PDL) is optional on the above listed vehicles.
The bed liner is applied directly to the truck bed as a GM Factory option. This process creates a bonded coating that
prevents water, dirt, dust and other contaminants from affecting the painted metal surface of the truck bed.
The black finish resists degradation from exposure to sun light, chemicals, and other environmental factors, while
providing a texture that prevents slippage or movement of goods. The coating also resists scratches, dents and
dings that would damage a regular painted surface. This type of liner requires no repositioning over time.
Unlike other aftermarket spray-in bed liners, this product has been specifically designed and tested for General
Motors trucks according to OEM specifications.
Note: The spray-in bed liner was not designed for use with the GM Accessory Cargo Management System that was
offered in 2012 and prior models.

Care Instructions
Important: Spray-in bed liners are permanent coatings that bond to the truck beds and other surfaces that are not
removable. Promptly rinse the bed liner surface following a chemical spill to avoid permanent damage following long
term exposure of the chemical.

Caution: Do not use silicone-based protection products to clean your bed liner as they may reduce the effectiveness
of the slip resistant texture and may lead to an injury. Silicone based materials may also degrade the spray-in bed
liner surface.
The shine and luster of the bed liner can fade from oxidation, road dirt, heavy-duty hauling, and hard water stains. To
help keep your bed liner looking and performing well, it is recommended that the bed liner can be cleaned at the
same time and manner as the rest of the vehicle, simply by washing using a mild detergent and spraying the liner
out. Automatic car wash residue may leave a white film. This can be removed with normal washing and brushing if
needed. This is considered vehicle maintenance.
A specific Silicone free bed liner conditioner is available through your GM dealership. See procurement procedure
below. The conditioner is available directly through the supplier, not through Customer Care and Aftersales Parts.
To restore the original appearance, wash the bed liner with a mild detergent. Once the liner is dry, apply the silicon
free bed liner conditioner (note it will spray on blue, it will dry clear) and let dry.

Application Details
The photos below show the areas that are covered by the spray-in bed liner. These should be used as a guideline
when making any repairs or answering customer questions concerning bed liner coverage areas.

Important: ONLY for vehicles receiving the spray-in bed liner (RPO CGN, PDL), a production change was implemented at the three full size truck plants which eliminated the application of seam sealer and basecoat to the
pickup bed floor. The change was implemented at Fort Wayne Assembly in April 2015, and at the Silao and Flint
plants in May 2015. Examples of the different appearance are shown in the graphic above. Vehicles built prior to the
change (1) will have a wide bead of seam sealer visible, whereas those built after (2) will not. The difference is
cosmetic appearance only, and the integrity of the spray-in liner is the same for both applications.
Because the bed liner material is sprayed on evenly, any variation in the bed such as seam sealer or spot welds in
the sheet metal will show underneath the spray on coating. This is an expected condition. The coating does not
completely fill in these variations.

Repair information
Bed liner repairs should be handled similar to other body repair and sublet to an appropriate vendor (identified on the
website below) or performed by the dealer (if proper equipment and skill set are available). This includes warranty,
New Vehicle Damage claims, customer pay and collision repairs. Additional information is provided in this bulletin to
clarify the repair process and supplier information.
Repairs to the spray-in bed liner fall into small or large categories. This will determine how the repair procedure will
be performed. Any damage to the underlying sheet metal must be repaired (including corrosion protection) prior to
repairing the bed liner material.
Most larger repairs will likely be performed by the approved Ultimate Linings authorized dealer network facilities and
submitted as a sublet repair if it is warranty or New Vehicle Damage related. These facilities can be found in the

2968698

1. Use a utility knife or screwdriver to remove any loose debris from the repair area. Bevel the edge of the repair
area with the utility knife.
2. Use a prep solvent to clean the area and allow to dry.
3. Place a large paper shop towel next to the repair area.
4. Shake the cartridge material to ensure proper mix and insert into the gun.

5. Purge the mixing tip away from the repair area (on the towel) to ensure proper material mix. Pump the cartridge
at least 3 times verifying there are no striations in the material to ensure proper mix. The material should be a
solid black color.

2968703

6. Noting the viscosity of the repair material, moving from the towel to the repair area, use a slow bead to fill the
entire repair area from the outer edges, spiraling into the center moving back to the towel leaving no tail of the
material on the repair area.
If the repair area is overfilled the edges can be feathered out using an edge of the textured pad.
It is better to slightly overfill the repair area.

7. Place the textured pad over the repair area and apply firm and even pressure for a minimum of 2 minutes.

2968709

8. Using a small block, such as a piece of 2 x 4 wood, allows for a more even pressure application.

9. Release the pressure and slowly remove the pad. If any material sticks to the pad, it can be removed once dry.
10. When completed, wait approximately 10 minutes then apply bed liner conditioner to the repaired area if required
to blend the color of the repair with the existing bed liner.

2968711

11. Long tears are handled in the same way but broken down into smaller sections to allow enough time to
complete the section within the cure time of the material and to be small enough to be covered by the textured
pad.
12. Left over unmixed material can be kept properly sealed for up to 30 days.
Important: If the material does set in 2 minutes, or does not harden in 30 minutes, the A and B portion of the repair
material did not mix properly. If this occurs, clean the affected area with solvent and reapply the repair material
making sure there is a good mix (all black in color) using a new tip.

Large Repairs
Large repairs are best performed by an approved Ultimate Linings authorized dealer network facility. The Claim must
be submitted as a sublet repair if it is warranty or New Vehicle Damage related. These facilities can be found in the
following contact information: www.gmbedlinerrepair.com/ or Ph. 1-800-989-9869 (Domestic or International) Let the

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
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 your GM dealer for information on whether your vehicle may benefit from the
information.
