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 Mazda says.
After you access the body repair manual, you are able to locate the corrosion protection information in the body repair manual (BRM) under the General Information section. Vehicle-specific information on where and how to restore corrosion protection is found under: Anticorrosion, Sound Insulation, and Vibration Insulation.
To locate where to apply corrosion protection, go to: Body and Accessories ➤ Body Structure ➤ Water-Proof and Rust Preventive. This is where Mazda provides documents that show where to apply seam sealer, undercoating, and cavity wax.
Adhesive locations can be found under: BRM ➤ Body And Accessories ➤ Weld Bond. Mazda states: "If the steel plate is replaced, apply adhesive to the positions shown in the figure."
Mazda does not specify any particular brands of corrosion protection. Mazda simply states: “apply rust inhibitor (wax, oil, etc.) to the back of the welded areas"
Always follow OEM repair procedures for all repairs. Failure to follow corrosion protection guidelines can lead to the premature failure of a repair. Using the proper corrosion protection ensures a complete, safe, and quality repair.
