Meguiar’s new Trailer Corrosion Protectant will help your boat’s chariot last longer, and protect it from salt spray, rust and corrosion. It creates a barrier against corrosion on both coated and uncoated metal surfaces for months. To use, simply shake the canister and apply it evenly to the cleaned surface. The self-leveling product will spread and coat uniformly on the trailer. It’s able to cover hard-to-reach components such as bolts, screws and tight trailer corners. Additionally, this easy-to-use formula will not harm trailer wiring, paint or wrapped surfaces.
