Corrosion Protection Guidelines: Subaru

A key factor in collision repair is making long-lasting repairs. When a vehicle is repaired, many areas of corrosion protection are disturbed. This creates corrosion hot spots that left untreated will lead to corrosion and potentially a repair failure. However, there are certain precautions that can be taken to safely and properly restore the corrosion protection throughout the repair process. OEMs often give specifications on restoring corrosion protection. These specifications generally include seam sealer, adhesives, foam fillers, and cavity waxes. Let’s take a look at what Subaru says.

Subaru has information on corrosion protection and seam sealers in the vehicle-specific body repair manuals. Here you can find what product to use, how much to apply, and where to apply. Subaru has specific brands of seam sealer, undercoats, and cavity wax (anticorrosion wax). For seam sealer, Subaru specifies Three Bond 4101 (004403063). For undercoat they specify PVC (NT guardcoat 5900FL) and for cavity wax, Subaru specifies Rust Stop aerosol (K0877YA015). Per our contact at Subaru, these products are available through Subaru dealers. The recommendations are found in vehicle-specific BRM index under their respective names: Body Sealing, Undercoats or Anticorrosion Wax.

Always follow OEM repair procedures for all repairs. Failure to follow corrosion protection guidelines can lead to premature failure on a repair. Using the proper corrosion protections will ensure a complete, safe, and quality repair.
