Fluid Film Rust and Corrosion Protection
The characteristic that impressed us the most is its excellent creeping effect, which helps the oil penetrate into the deepest layer of rusty areas. Also, its chemical properties are so advanced that it wouldn’t dry, break, or freeze once applied.
Even though it isn’t a rust remover, we approve of its capability to inhibit rust from arising. Not only that, but it also hampers the progress of the existing hardened corrosion, even in tiny parts like nuts, bolts, shafts, etc.
Do you know what else makes Fluid Film Rust and Corrosion Protection stand out? It’s a fact that it is utilized in vehicles that are used in both marine and air operations.
Just to make it clear, this oil has certain side effects too. For instance, its smell is off-putting.
Also, it is to be noted that this product is based on lanolin, which is a wool wax. Hence, anyone who is allergic to wool should avoid it at any cost.
Another downside of this particular undercoating is that the spray cans are not as good as the oil itself. Many consumers have complained about the defective nozzle of the cans, which made the application a bit annoying and tiring.
Despite these shortcomings, Fluid Film Rust & Corrosion Protection is one of the most affordable undercoatings.
- It is water-repellent and protects the metal surfaces from excessive moisture.
- It doesn’t cause damage to any of the rubber or plastic-based parts in your vehicle.
- The product doesn’t have any warranty.
- It is not biodegradable.
Krown Rust Control & Lubricant
Krown Rust Control & Lubricant is another rust-proofing product that has been gaining a lot of popularity past few years. It can be used in a variety of vehicles and machinery in both personal and industrial areas.
Thanks to its high opacity and creeping properties, the application process will be simple even if the rust is deeply rooted. Not to forget, we were also able to stop the fast accumulating rust on our vehicle with one application.
Another trait that caught our attention is that it didn’t come off even after the full rainy season because the product is highly water-resistant. The petroleum film won’t tear and crumple under any given temperature.
But you have to keep a few things in mind before you choose this product. The first is that it can unnaturally expand the rubber items in your vehicle.
Pro-tip:– Cover up the areas that have rubber like weather stripping, bumpers, bushes, etc. with a plastic foil sheet before spraying the oil. Even after this, if some of it reaches the parts, coat them with silicone to avoid harm.
We also noticed that oil dripped after the application, which made a bit of a mess. Other than that, it qualifies as a good rust-proofing product.
- It comes with a great warranty for different types of vehicles.
- There is no risk of skin allergy.
- Easy to use aerosol spray cans.
- It lacks versatility, which means it cannot be used on surfaces other than metal.
