Fluid Film Rust and Corrosion Protection is a thick, wax-based liquid designed to prevent rust and lubricate metal parts, making it a strong candidate for protecting your mower deck from corrosion. Its main ingredients include a special wool-wax formula combined with oils, creating a coating that doesn’t dry out or crack over time. This means it can provide long-lasting protection, even in wet or harsh conditions, which is especially useful if your mower is often exposed to moisture or outdoor elements.

The product is applied as a liquid, and because it stays wet and oily rather than drying hard, it continues to protect by penetrating into metal surfaces and displacing water. This feature helps prevent rust from forming under the coating. However, because it doesn’t fully dry like paint or a hard enamel coating, it may attract dirt or debris, which might require occasional cleaning. Also, the application is manual and could be a bit messy, given its oily nature and 5-gallon pail packaging, so it's best suited for users comfortable handling larger quantities for multiple applications. Drying time is not quick since the product remains wet to maintain protection, which means you should allow some time before using the mower again.

Fluid Film excels in durability due to its ability to keep metal parts lubricated and rust-free without harmful solvents, making it a safe and effective choice for mower decks exposed to tough environments. If you want a coating that both protects and lubricates without cracking or peeling, and you don’t mind the oily finish, this product is worth considering.

The POR-15 Rust Preventive Coating is a reliable choice for those needing to protect their mower decks from rust and corrosion. It stands out due to its unique curing process that takes advantage of moisture to create a tough, durable finish that prevents rust permanently. This feature makes it suitable for environments where the mower might be exposed to moisture frequently. The non-porous and chemical-resistant qualities of the coating contribute to its durability, providing a strong barrier against water, chemicals, and salt, which can be common in outdoor settings.

Application requires a three-step process for the best results, starting with surface cleaning and preparation. Users should be aware that the coating needs to be applied in thin layers, at least two coats, with a drying time of about 2 to 5 hours before it can be recoated or top coated. This method ensures a good bond with the metal surface, although it might involve more effort and time compared to simpler spray-on products.

The product is versatile, with a semi-gloss black finish that can be used on both interior and exterior surfaces. However, users should note that it requires a topcoat if the surface is exposed to UV light to prevent degradation. The 16-ounce can provide ample coverage for small to medium-sized mower decks, but larger decks may require additional cans. The application process might be considered labor-intensive for those seeking a quick solution. Nonetheless, for DIY enthusiasts and professionals seeking long-term protection, POR-15 offers a comprehensive solution.
