Warning:
When applying sound deadeners, or anti-corrosion materials due care and preventative measures must be exercised to prevent
any material from being sprayed into door and quarter panel mechanisms such as door locks, window run channels, window regulators and
seat belt retractors, as well as any moving or rotating mechanical or suspension parts on the underbody, particularly the parking brake
cable. After material application, be sure that all body drain holes are open. Improper application may increase chance of corrosion damage
or limit the operation of moving parts, resulting in personal injury.
Any procedure that disturbs these special treatments, such as panel replacement or collision damage repair operations, may leave the
metal unprotected and result in corrosion. Proper recoating of these surfaces with service-type anti-corrosion material is essential.
After repair and/or replacement parts are installed, all accessible bare metal surfaces must be treated with metal conditioner and reprimed.
Refer to the GM Approved Refinish Materials book which identifies the paint systems you may use.
The latest revision of the GM Approved Refinish Materials booklet is located on the Goodwrench website at www.gmgoodwrench.com.
Anti-corrosion compounds are light-bodied materials designed to penetrate between metal-to-metal surfaces, such as pinch-weld joints,
hem flanges, and integral panel attaching points where metal surfaces are difficult to coat with conventional undercoating materials, and
are inaccessible for painting. The materials that are suitable for interior and exterior are listed in the chart below. Conventional
undercoating is recommended in order to coat large areas, such as replacement door and quarter outer panels, floor pan sections, lids,
hoods, fenders, etc. During undercoating operations, care should be taken to prevent the material from being sprayed into door and
quarter panel hardware mechanisms, such as door locks, window run channels, window regulators, and seat belt retractors. On the
underbody, the material should not be applied to any moving or rotating part, energy absorbing bumper components, or shock absorbers.
After undercoating, ensure that all body drain holes are open.

These sealers are intended to prevent water and dust from entering the vehicle and also are anti-corrosion barriers. Sealers are applied to
such areas as rear compartment lid hem flanges, wheelhouse, quarter outer, floor, cowl, roof, and various other panel to panel attaching
points. The originally sealed joints are obvious and any damage to these sealed locations should be corrected by resealing. Attaching points
of new replacement panels should be resealed. Replacement lids and doors will also require sealing in the hem flange areas.
Flanged joints, overlap joints, and seams should be sealed using a quality sealer of medium-bodied consistency. The sealer used must
retain its flexible characteristics after curing and be paintable.
