POR-15: The Heavy-Duty Rust Converter and Coating
POR-15 is a high-performance, rust-converting coating that creates a rock-hard, non-porous surface. It’s designed to be applied directly to rusted metal, making it an excellent choice for use on vehicles, machinery, and other metal surfaces prone to rust.
Pros of POR-15
- Permanently seals rust: POR-15 doesn’t just prevent rust; it converts existing rust into a hard, non-porous surface.
- Highly durable: Once cured, POR-15 creates a tough, abrasion-resistant coating that can withstand harsh environments.
- Wide temperature range: POR-15 can be used in high-temperature applications, making it suitable for use on exhaust systems and other heat-generating components.
- Paintable: You can paint over POR-15, allowing you to create a seamless finish on your vehicle or equipment.
Cons of POR-15
- Application process: Applying POR-15 requires careful surface preparation and multiple steps, which can be time-consuming.
- Potentially hazardous: POR-15 contains chemicals that can be harmful if not used with proper safety precautions, such as gloves and adequate ventilation.
Comparing Fluid Film And POR-15 for Rust Protection
When it comes to rust protection, both Fluid Film and POR-15 have their unique strengths and weaknesses.
Fluid Film is an excellent choice for those looking for an eco-friendly, easy-to-apply solution that provides long-lasting protection.
On the other hand, POR-15 is better suited for those dealing with existing rust and needing a more permanent, heavy-duty solution that can withstand high temperatures and harsh conditions.
While both products offer effective rust protection, they serve different purposes and are best suited for different applications. If you’re looking for an all-around rust preventative that’s easy to apply and environmentally friendly, Fluid Film is your best bet.
If you need a heavy-duty rust converter and coating that can handle high temperatures and provide a durable, paintable surface, POR-15 is the clear winner.
Application Tips for Fluid Film and POR-15
To get the best results from both Fluid Film and POR-15, it’s crucial to follow the recommended application guidelines. Here are some tips to help you apply each product effectively:
Fluid Film Application Tips
- Clean the surface: Before applying Fluid Film, clean the surface to remove dirt, grease, and loose rust. A clean surface will allow the product to adhere better and provide more effective protection.
- Apply evenly: Spray or brush on an even coat of Fluid Film, ensuring complete coverage. You can also use your hands to apply the product, but be sure to wear gloves.
- Allow it to dry: Give Fluid Film time to dry and set. This usually takes about an hour, but it may take longer in colder or more humid conditions.
POR-15 Application Tips
- Prepare the surface: Thorough surface preparation is crucial for effective POR-15 application. Remove loose rust, dirt, and grease using a wire brush, sandpaper, or a suitable cleaner/degreaser.
- Apply a metal prep: Use a metal prep solution, such as POR-15 Metal Prep, to etch the surface and ensure better adhesion of the coating.
- Apply thin coats: Apply two to three thin coats of POR-15, allowing each coat to dry for at least two hours before applying the next one. This will ensure proper curing and a durable, long-lasting finish.
- Topcoat if necessary: If your project will be exposed to direct sunlight, apply a UV-resistant topcoat over the POR-15 to prevent sun damage.
Fluid Film is primarily a rust preventative, meaning it works best when applied to clean, rust-free surfaces. While it can slow down the rusting process on already rusted surfaces, it doesn’t convert or seal existing rust like POR-15 does.
There are a few alternatives to POR-15 that provide similar rust-converting and sealing properties. Some popular options include Rust Bullet, KBS RustSeal, and Eastwood Rust Encapsulator. Each of these products has its own set of pros and cons, so it’s essential to research and compare them based on your specific needs.
Fluid Film’s longevity depends on the environmental conditions and the thickness of the application. In general, a single application of Fluid Film can provide protection for up to a year in normal conditions. However, if exposed to harsh environments or extreme weather, reapplication may be necessary more frequently.
Fluid Film stands out among rust preventatives for several reasons:
1. It’s made from natural ingredients, making it an eco-friendly and non-toxic option.
2. It’s easy to apply and doesn’t require any special equipment or surface preparation.
3. The product has self-healing properties, allowing it to maintain a continuous protective barrier even when damaged.
4. Fluid Film offers long-lasting protection against rust, often lasting up to a year in normal conditions.
These features make Fluid Film a top choice for those seeking a simple, effective, and environmentally friendly solution for rust prevention.
Yes, Fluid Film is a proven rust preventative that has been trusted by professionals and DIY enthusiasts alike for decades. Its unique formula provides a long-lasting barrier against moisture and corrosive elements, effectively preventing rust from forming on metal surfaces. With proper application, Fluid Film can keep your vehicle, machinery, and equipment protected from rust and corrosion for an extended period.
The Bottom Line
Ultimately, the choice between Fluid Film and POR-15 comes down to your specific needs and preferences. Both products offer effective rust protection, but they cater to different applications and situations.
Fluid Film is an excellent option for those looking for an easy-to-apply, eco-friendly, and long-lasting rust preventative. It’s ideal for general maintenance, undercoating vehicles, and protecting metal surfaces from moisture and corrosion.
On the other hand, POR-15 is better suited for heavy-duty applications where existing rust needs to be converted and sealed, and a durable, high-temperature-resistant coating is necessary. It’s perfect for restoring rusty vehicles, machinery, and equipment, as well as protecting high-heat components like exhaust systems.
By understanding the unique features and benefits of both Fluid Film and POR-15, you can make an informed decision about which rust protection product is best suited for your needs.
