Corrosion Protection for Metal Panels with Dealer Installed Accessories Fastened by Drilled Holes

This bulletin is being revised to add additional models, model years and inform dealers that the name of GM Vehicle Care Super Lube® with PTFE has changed to GM Vehicle Care Synthetic Lubricant with Teflon®. Please discard Corporate Bulletin Number 03-00-89-008B (Section 00 -- General Information).

Important: The product formerly known as GM Vehicle Care Super Lube® with PTFE has changed the name to GM Vehicle Care Synthetic Lubricant with Teflon®.

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.

In all cases, GM Vehicle Care Synthetic Lubricant with Teflon® performed the best at preventing corrosion in fastener to panel interface holes and is now the official GM recommended product. It is recommended toapply the GM Vehicle Care Synthetic Lubricant with Teflon® to any hole and fastenerbefore installingthe fastener into the drilled attaching hole or inside the metal panel.

Important: GM Vehicle Care Synthetic Lubricant with Teflon® is the only product recommended and required by GM for the corrosion protection of metal panels where fasteners will be added to metal panels.
