Corrosion can occur after collision repair when metal surfaces, fasteners, or components are exposed to moisture, road salt, chemicals, or other corrosive elements. The risk can increase when a repair joins dissimilar metals, such as aluminum and steel. Areas that are difficult to access after assembly can be especially vulnerable if they are not properly protected.

Corrosion prevention starts with proper surface preparation and protection during reassembly. Clean and dry the repair area, then protect vulnerable surfaces, fasteners, drilled holes, and areas where dissimilar metals meet. Using an appropriate corrosion barrier can help isolate dissimilar metals and keep moisture from reaching the joint. For repairs involving aluminum and steel, Eck from Austin Hardware creates a protective barrier between dissimilar metals and helps protect against galvanic corrosion.

Apply corrosion protection during reassembly, while mating surfaces, drilled holes, fasteners, and other vulnerable areas are still accessible. This helps protect areas that may be difficult or impossible to reach once the repair is complete.

Galvanic corrosion occurs when two dissimilar metals are joined and exposed to moisture or another electrolyte, such as road salt. Because the metals have different electrical potentials, one metal can corrode more rapidly than it otherwise would. This can be a concern in vehicle and collision repair applications where aluminum and steel are joined in the same assembly.

Aluminum and steel have different electrical potentials. When they are in direct contact and exposed to moisture or another electrolyte, a galvanic reaction can occur, accelerating corrosion. Preventing direct contact between the metals and limiting moisture exposure help reduce the risk. This can be accomplished with protective coatings, isolating materials, corrosion-resistant hardware, and other protective measures. Eck provides an additional barrier between dissimilar metals and can be applied to mating surfaces, drilled holes, and fasteners during assembly.

Yes. Eck is designed for applications where dissimilar metals may be exposed to moisture and corrosion, including automotive applications. In collision repair, it can be used during reassembly to protect vulnerable joints, fasteners, drilled holes, and other areas where dissimilar metals meet.

Eck can be applied to areas where dissimilar metals meet or where moisture could reach the joint. Common collision repair applications include drilled holes, fasteners, mating surfaces, and areas behind brackets, hinges, latches, light assemblies, and other mounted components. The goal is to protect areas that may be difficult to access once the repair is complete.

Yes. You can apply ECK to bolts, screws, and other fasteners during assembly. Applying Eck to fastener threads and drilled holes helps create a protective barrier while also providing anti-seizing properties.

Yes. Eck is dielectric and can be used on electrical connections to help protect against corrosion. It can also be used with lighting components, provided it is applied according to the manufacturer's instructions and applicable vehicle repair requirements.
