Our Clients Thought

I've been restoring a 1967 Ford F-100 that had been sitting in a barn for decades, and let me tell you - the rust situation was DIRE. I'd tried everything under the sun before discovering Corroseal. Skeptical at first (aren't we all with "miracle" products?), but wow, this stuff actually works exactly as advertised! Applied it to the truck bed that was basically more rust than metal, and it was fascinating watching the chemical reaction turn the surface dark. Left it overnight, and by morning I had this perfect primer surface. The best part? It's been 8 months since I finished the project and there's absolutely zero rust returning, even in areas I was worried about. The water-based formula meant no horrible fumes in my garage, which my wife greatly appreciated. Worth every penny of the $29.42 I spent on the quart - which, by the way, covered way more surface area than I expected. If you're on the fence about this product, just buy it already. Your future self will thank you.

OK so my wrought iron patio furniture was looking absolutely terrible after 3 Minnesota winters... I'm talking major rust issues that were getting worse every season. I'm not super handy but I didn't want to replace everything because these pieces were expensive! I read about Corroseal online and decided to give it a shot. I ordered the Water-Based 1 Quart Rust Converter and Metal Primer 2-Pack for $48.32 because I had multiple pieces to do. It arrived quickly and the instructions were super clear. The application process was really satisfying tbh? You literally watch the rust transform as you apply it! It turned this gross rusty color into this dark surface that was ready for paint. I chose a pretty teal color to go over it and OMG the difference is night and day! My neighbors have all asked what I did! The best part is that it's been through a rainy fall season already with zero signs of rust returning. I'm definitely keeping Corroseal on hand for future projects. Truly worth every penny for saving my furniture!

Having been in commercial construction for over 22 years, I've witnessed countless products make big promises about rust treatment only to disappoint in real-world applications. Corroseal, however, stands apart from the competition in meaningful ways. Our firm recently utilized the Cleaner and Degreaser/Rust Converter Kit (Model# CORRQTCOMB-2PK) on a challenging restoration project involving exposed structural elements. The cleaner effectively removed decades of accumulated grime, while the converter transformed severely rusted surfaces into paintable substrate with remarkable efficiency. What impressed me most was the reduction in labor hours. Traditional methods would have required extensive sandblasting and multiple primer applications; Corroseal eliminated these steps entirely. The water-based formulation also meant minimal respiratory protection requirements for my crew. The cost-benefit analysis is straightforward: the $45.11 kit saved approximately 22 labor hours on this project alone. From a contractor's perspective, this product delivers exceptional value while producing professional-quality results. Highly recommended for commercial applications where time constraints and durability requirements are paramount.

Y'all... I inherited my grandfather's old woodworking tools and they were in ROUGH shape! Like, orange rust everywhere, couldn't even read the markings anymore kind of shape. I was heartbroken thinking they were beyond saving. Then my neighbor (bless him!) recommended Corroseal. I picked up a quart at Home Depot ($29.42) and spent a weekend working on these treasures. Let me just say... MIND. BLOWN!!! These tools that I thought were goners are now cleaned up and actually USABLE! The hand planes, chisels, and even the old cast iron parts all responded amazingly well to the treatment. The stuff is super easy to use too - you just brush it on and wait. It does all the work! And it's not stinky or dangerous like some other rust treatments I've tried in the past. My husband was impressed with how it turned the rust black and created this nice surface that took paint perfectly (for the non-working parts). These tools mean the world to me sentimentally, and thanks to Corroseal, they'll be around for another generation. If you've got old metal treasures that need saving, don't hesitate!!!

As the owner of a 32' sailboat moored in the challenging saltwater environment of Puget Sound, I have engaged in a perpetual battle against corrosion. Previous rust treatments provided merely temporary solutions until I discovered Corroseal's Water-Based Rust Converter. I initially applied the product (Model# 82320) to several corroded deck fittings and stanchion bases exhibiting significant deterioration. The application process proved straightforward; the product's viscosity allowed precise application without excessive dripping or waste. Within hours, the transformation was evident – the rust had chemically converted as promised. Most significantly, after applying appropriate marine topcoats, these treated areas have now withstood nine months of harsh saltwater exposure without deterioration. This performance significantly exceeds any previous rust treatment I've utilized in my 17 years of boat ownership. The water-based formulation also proves advantageous in the confined spaces of marine applications, minimizing noxious fumes. While the initial investment of $29.42 may exceed some alternatives, the durability of the results justifies the expense. I have subsequently purchased the two-pack kit for additional applications throughout my vessel.

FAQs

Corroseal® chemically converts rust (iron oxide) into a stable compound while simultaneously priming the surface. Unlike rust removers that just strip rust away, our converter transforms it into an inert, paintable surface in one step.

One quart of Corroseal® Rust Converter typically covers approximately 200-250 square feet of smooth surface. Coverage may vary depending on surface roughness, rust severity, and application method.

Minimal surface preparation is needed! Just remove loose rust, scale, and flaking paint with a wire brush. No extensive sanding or sandblasting required—that's the beauty of Corroseal®!

Corroseal® begins converting rust immediately, with visible darkening occurring in minutes. Allow 24 hours for complete curing before applying topcoat paint for best results.

Absolutely! Our formula has the perfect consistency to adhere to vertical surfaces without excessive dripping or running. Apply in thin, even coats for best results.

Yes! Being water-based, Corroseal® produces minimal odor and contains no harsh solvents, making it suitable for indoor use with proper ventilation. Always follow safety guidelines on the label.

Our standard converter is perfect for most projects. The kit includes both our converter and our specialized cleaner/degreaser for heavily contaminated surfaces where oils or chemicals might interfere with conversion.

Definitely! Corroseal® is ideal for automotive restoration, including frames, floor pans, body panels, and undercarriage components. Many restoration professionals trust it for classic car projects.

While Corroseal® provides temporary protection alone, we recommend applying a quality topcoat paint for maximum durability and weather resistance, especially for outdoor or marine applications.

Unopened Corroseal® maintains its effectiveness for approximately 2 years when stored properly in a cool, dry place. Once opened, we recommend using within 12 months for optimal performance.
