Corrosion Protection Guidelines: Toyota/Lexus

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 Toyota/Lexus says.

Toyota/Lexus does not specify the type of product to be used for restoring corrosion protection. However, there are typically two areas within the vehicle-specific body repair manual in which to find information on corrosion protection. The first is located under: General ➤ Work Notices and Precautions ➤ Anti-Rust Treatment After Installation of Body Structure Parts or Outer Panels. The other area is located in Vehicle Exterior ➤ Painting/Coating. Additional documentation is located in CRIB #186 Corrosion Prevention for Collision Repair.

There are guidelines given as to when corrosion protection should be applied for example, per the 2017 Toyota Highlander body repair manual: “For water-proofing and anti-rust measures, always apply the body sealer to the body panel seams and hems of the doors, hood, etc.” The procedure will usually include hints and illustrations to aide you in the application process.

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.
