Corrosion Concerns

Frequently, dealer installed accessories, whether aftermarket or GM-approved, may require drilling holes into the body panels or supports to

complete installation. Whenever you drill into a metal surface, the corrosion resistance of that panel is compromised. Testing was conducted to

determine the best method used to protect the fastener-to-panel mounting holes from future corrosion. Several commercially available sealers and

coatings were evaluated.

Recommendations

In all cases, GM Vehicle Care Super Lube(R) with PTFE performed the best at preventing corrosion in fastener to panel interface holes and is now

the official GM recommended product as shown in the above illustration. It is recommended to apply the GM Vehicle Care Super Lube(R) with

PTFE to any hole and fastener before installing the fastener into the drilled attaching hole or inside the metal panel.

Important

GM Vehicle Care Super Lube(R) with PTFE is the only product recommended and required by GM for the corrosion protection of metal

panels where fasteners will be added to metal panels.
