Corrosion Protection Guidelines: Fiat Chrysler Automobiles (FCA)
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 Fiat Chrysler Automobiles (FCA) says.
Information on corrosion protection can be found in the vehicle-specific body repair manuals, on both the free and pay service information websites. Here there are documents listing what products are required, along with when and how to apply the corrosion protection. Per the FCA repair manual: “Corrosion protection must be restored during a repair anytime it may have been compromised. All areas that have been subjected to structural pulls, clamping, straightening, welding, or any other any other operation that may have imparted damage to the corrosion protection system will need to be addressed.” FCA also has a procedure in certain repair manuals for how to remove NVH foam prior to doing repairs in that area, due to its’ flammable nature. Examples of vehicles with this procedure are the 2017 Chrysler Pacifica and the 2017 Jeep Cherokee.
FCA specifies several different products for restoring corrosion protection. Some products that are recomended by FCA are as follows:
- Structural adhesive – Lord Fusor 2098, LORD Fusor 112B, or 3M 08116
- Anit-flutter foam – Mopar 04864015AB, LORD Fusor 121, 3M 04274, or equivalent
- NVH foam – Mopar 05142864AA, LORD Fusor 130, or 3M 8463
- Seam sealer – Mopar 04318026, LORD Fusor 129, or 3M 08308
- Cavity wax – Mopar 68042970AA or 3M Rustfighter 08891
- Undercoating – Mopar 05093417AA or equivalent
Per the FCA repair manual: “If it is unclear whether the original sealing material between the flanges is strictly a sealer or structural adhesive, always default to a structural adhesive”. “All hem flanges on closure panels should be sealed whether sealer is apparent or not. This includes those disturbed during the repair, and those on new replacement panels. Either duplicate the existing bead in shape or size, or where one is not obvious, seal the hem flange in a discrete fashion.”
FCA has enhanced the most recent body repair manuals (BRM) with color coordinated diagrams to help technicians easily identify what adhesives, foams, and seam sealers goes where during repairs. The enhanced graphics are labeled as followed:
- Structural Adhesive – Red
- Anti-Flutter Adhesive – Green
- Seam Sealer – Blue
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.
