Hi! I would recommend zinc coating/galvanizing for outdoor automotive components. The method of applying a layer of zinc to steel surfaces is highly efficient in providing exceptional corrosion protection. It’s a tried and tested solution that reliably preserves the integrity of automotive parts, ensuring they endure harsh outdoor conditions over time.

Additionally, I’d like to suggest considering anodizing as an alternative solution. Anodizing, particularly for aluminum parts, creates a protective oxide layer on the surface, greatly enhancing durability and corrosion resistance, offering long-lasting protection against rust and degradation.

I’ve had great success with a zinc-rich primer followed by a high-quality weather-resistant topcoat for outdoor automotive components. The primer acts sacrificially, protecting the metal, while the topcoat adds an extra layer of defense against corrosion and UV damage. Make sure to prep the surface well before applying for the best results!
