and Accessories).
The process of removing dents from vehicles without painting has been around for many years. General Motors has evaluated many versions of this
process. A process using special tools that allow shallow dents to be removed without drilling holes in the body, by removing components like hood
insulators, tail lamps, and headlamps is recommended. This process is appropriate for the majority of panels with reasonable access to the back side
of the damaged area. The special tools and procedures used with paint-less dent repair that have been developed will remove the dents while
eliminating the need to fill, paint, or replace the panel.
New developments in this technology have also made dent removal possible in areas where there is minimal or zero access to the back side of the
panel by use of "glue stick" dent removal. From the outside of the panel, adhesive material is placed over the dent, allowed to cool and the dent can
be pulled back to its original contour without paint damage. Common areas for "Glue Stick" dent removal are roof rails, pickup box bed rails, roof
skin near stationary glass, etc. This process requires no drilling of holes or removal of vehicle components for access. These type of repairs will
eliminate concerns about paint and factory corrosion durability and significantly reduce repair and disclosure amounts. This type of procedure has
been thoroughly evaluated and the repaired parts were tested for negative impact. No negative impact was found.
Important
The removal of structural components or drilling of holes in any panel is not recommended and may void the General Motors Corrosion
Warranty.
Evaluating Damage
Note
Paint-less dent repair should be used for both warranty "out dent" repair and transportation damage where damage type code "14- dented no paint
damage" is used on the delivery receipt. Dents which exceed severity code 3-Damage over 3 inches (8 cm) up to and including 6 inches (15 cm) in
length/diameter may still require conventional paint repairs.
Appropriate uses for paint-less dent repair include the following conditions:
- Repair of minor transportation damage dents.
- Dents with no broken paint on the surface. Be sure to inspect the paint for cracks, a magnifying glass may be helpful; GM suggests using a 4x
magnifying glass.
- Large or small dents, soft dents in body lines and contoured areas that allow reasonable access to the back side of the damaged area.
- Dents that do not require structural part removal, and where "glue stick" dent removal is successful.

Inappropriate uses for paint-less dent repair include the following situations:
- Dents that include cracked paint.
- Dents that require holes to be drilled.
- Dents that require structural parts to be removed.
- Sharp dents in contoured areas, dents on the edge of panels, or dents in zero-clearance areas where glue stick dent removal has been
unsuccessful.
Tools
Use tools that are high-quality, tempered steel with smooth polished, rounded tips. These will not damage the back side of the dented area.
Typically, these tools are shaped and bent in order to allow access to most areas of the vehicle without drilling holes in the body as well as provide
a clear view of the work area. Specialty lights are also used to highlight damaged areas.
