CORROSION PREVENTION AND SEALING
-6
STRUCTURAL SEALING
All the seals are fitted in the body-in-white areas, and after going through the paint baking process expand up to eight
times original size.
Replacing seals
As paint oven temperatures used in a repair workshop are significantly lower than those that are used during
manufacture of the vehicle, a different process is required to replace the seals in service.
After a repair that involves replacement of a section containing expanded foam, the new section must be injected
with an approved sound dampening foam. The sound dampening foam should be injected after paint refinishing and
application of cavity wax. When injecting the foam, ensure the foam fills a complete cross section of the cavity.
