After-Manufacture “Rustproofing”
Your vehicle was designed and built to resist
corrosion. Application of additional rust-inhibiting
materials is neither necessary nor required
under the Sheet Metal Coverage. GM makes no
recommendations concerning the usefulness
or value of such products.
Application of after-manufacture rustproofing
products may create an environment which
reduces the corrosion resistance built into your
vehicle. Repairs to correct damage caused
by such applications are not covered under your
New Vehicle Limited Warranty.
