Repairing Major Body Damage - Anti-Rust Treatment (After Painting)
1. Internal Anti-rust Treatment


Internal Anti-rust Treatment:

During collision repairs, body pulling and welding destroy the e-coat film on inner panels.
This will quickly allow rust to form on those panels. Thoroughly apply anti-rust agent on inner surfaces in the repaired areas prevent corrosion.
Always apply anti-rust agents a little beyond the actual repair areas.
For the basic locations of anti-rust agent application, refer to the model specific body repair manual:

?
Apply internal anti-rust agent through part installation holes, inner panel openings, grommet installation holes, etc. Apply anti-rust agent liberally until it bleeds through the panel mating seams.

?
When applying anti-rust agent to a wide area, use spray equipment specifically designed for anti-rust agent application and the most appropriate nozzle (360 degree nozzle, L nozzle, etc.).
