Corrosion Protection Guidelines: Honda/Acura

Corrosion Protection Guidelines: Honda/Acura

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 Honda/Acura says.

Both Honda and Acura have documents listing recommended products from 3M, Fusor, SEM, and Kent. This document is found under the Collision Repair Information & Industry Position Statements area of the Honda/Acura service website. Information on cavity wax and seam sealers can be found in the vehicle-specific body repair manuals, under: Rust Prevention. Foam and adhesive applications are identified within the part specific repair procedures. Per the Honda/Acura body repair manual:

  • "When applying sealant (seam sealer) to the engine compartment, the door openings, and the rear gutter, try to match the factory sealant (seam sealer).
  • Apply sealant (seam sealer) to any area that a replacement part will cover.
  • Do not spray an anti-rust agent (cavity wax) on the brake system components, exhaust system components and related parts, emission control devices in the engine compartment, ball joint covers, the fuel strainer, or exterior and interior parts.
  • Follow the anti-rust agent (cavity wax) manufacturer’s instructions."

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.
