The process of removing dents from vehicles without painting has been around for manyyears. General Motors has evaluated many versions of this process. A process usingspecial tools that allow shallow dents to be removed without drilling holes in thebody, 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 theback sideof the damaged area. The special tools and procedures used with paint-less dent repairthat 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 areaswhere there is minimal or zero access to the back side of the panel by use of “gluestick” dent removal. From the outside of the panel, adhesive material is placed overthe dent, allowed to cool and the dent can be pulled back to its original contourwithout paint damage. Common areas for “Glue Stick” dent removal are roof rails, pickupbox bed rails, roofskin near stationary glass, etc. This process requires no drilling of holes or removalof vehicle components for access. These type of repairs will eliminate concerns aboutpaint and factory corrosion durability and significantly reduce repair and disclosureamounts. This type of procedure has been thoroughly evaluated and the repaired partswere tested for negative impact. No negative impact was found.
Important:The removal of structural components or drilling of holes in any panel is not recommendedand may void the General Motors Corrosion Warranty.
Evaluating Damage
Note:Paint-less dent repair should be used for both warranty “out dent” repair and transportationdamage where damage type code “14- dented no paint damage” is used on the deliveryreceipt. Dents which exceed severity code 3-Damage over 3 inches (8 cm) up to andincluding 6 inches (15 cm) in length/diameter may still require conventional paintrepairs.
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 reasonableaccess to the back side of the damaged area.Dents that do not require structural part removal, and where “glue stick” dent removalis 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-clearanceareas 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 areshaped and bent in order to allow access to most areas of the vehicle without drillingholes in the body as well as provide a clear view of the work area. Specialty lightsare also used to highlight damaged areas.
GM bulletins are intended for use by professional technicians,NOT a "do-it-yourselfer". They are written to inform thesetechnicians of conditions that may occur on some vehicles, or toprovide information that could assist in the proper service of avehicle. Properly trained technicians have the equipment,tools, safety instructions, and know-how to do a job properly andsafely. If a condition is described, DO NOT assume that thebulletin applies to your vehicle, or that your vehicle will havethat condition. See your GM dealer for information on whetheryour vehicle may benefit from the information. | WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION |
