A coat of paint attaches itself so closely to the metal that moisture and oxygen cannot attack the surface, resulting in a much longer paint job. STEP 1 Remove any loose rust with a wire brush or wire wheel. Rust must be present for product to work. STEP 2 Spray or paint on Rust Kutter. STEP 3 Rinse & let dry. Dry conditions & low humidity should allow for a 24 hour drying time. STEP 4 Brush off any loose residue. You can repaint from here or leave area as is. Available in Gallons and Quarts Rust Kutter stops the oxidation process to prevent further rusting. Stop even the toughest rusting on ferrous metals, tools, farm equipment, railings, lawn furniture and truck beds.

And really, the price isn't bad when you consider the price of buying the ingredients separately and mixing it yourself would only save you a few bucks per gallon and probably not work as well. Basically this consists of ~%35 phosphoric acid, ~%5 citric acid, and some surfactants (alcohol and NP9.5) to help the solution penetrate the rust and scale. The citric acid helps dissolve the loose rust and make it water soluble, and the phosphoric acid reacts with the rust (iron oxide) converting it into iron phosphate, which is actually an anti-rust coating that is commercially applied to some steel products. If you prep properly by removing the loose rust and paint and making sure the surface is free of oils, you'll end up with all the rusty brown spots turning a satisfying black color, and the excess acid drying up to a white powder. Then you just rinse off the excess and optionally paint to protect the bare steel that didn't get converted. I bought this after watching a YouTube video that compared most of the "rust converting" products on the market, including the primers, aerosols, and acids. This blew the competition away. I had to try it for myself and I'm glad I did! You should wear gloves and eye protection while using it, as while it's the consistency of soapy water and comes in a household spray bottle, the spray will definitely sting your eyes, and if some spray dribbles out of the bottle onto your hands you can feel it dissolving the top layers of your skin like bleach (your fingers get slippery). However, it doesn't stink and it washes off easily with water. Note that this is not a "quick fix", the solution takes one to three days to convert the rust, and on heavily rusted objects you may need to apply two or three times, allowing the solution to dry in-between. But the results are amazing. My bottle saved a totally trashed wheelbarrow, protected another wheelbarrow that was starting to rust in the basket, fixed up my super rusty cast iron digging bar that I've had to previously grind every year, and cleaned up a bunch of rusty lug nuts, wheel mounts, and rims on an old car. And I still have 1/3 bottle left. I still plan to paint most of those objects for extra protection, but I'm a believer and will definitely be buying this again in the future. Now if you'll excuse me, I have some rusty lawn furniture and tools to hit next. Review: Very effective on pitted rust. - Works very well. On heavy rust you need multiple applications. Allow 24 hrs per application. Allow final application to sit 72 hrs. Scuff, clean with wax n grease remover /lacquer thinner or the like and prime/paint. ## Features - A rust converter is a specialized product designed to convert rust into a more stable and non-reactive compound that can be painted over. - Rust converters work by chemically reacting with the rust, breaking it down into a stable, black compound that can be easily painted over. - This product is ideal for use on metal surfaces that have rusted, such as car bodies, metal tools, and outdoor equipment. - Rust converters can also be used to help prevent further rust formation by creating a protective barrier on the surface of the metal. - Rust converters are easy to apply and can be used with a brush, roller, or spray gun, depending on the size and complexity of the surface being treated. - Available in Quarts & Gallons ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001U1KDDC | | Best Sellers Rank | #4,656 in Automotive ( See Top 100 in Automotive ) #20 in Care Corrosion & Rust Inhibitors #319 in Oils & Fluids | | Brand | Rust Kutter | | Brand Name | Rust Kutter | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.4 out of 5 stars 2,325 Reviews | | Item Form | Spray | | Item Volume | 32 Fluid Ounces | | Item Weight | 2.76 Pounds | | Manufacturer | Sanco Industries | | Material Feature | Spray | | Material Features | Spray | | Model Number | 08088 | | Number of Items | 1 | | Part Number | 08088 | | Size | 32 Fl Oz (Pack of 1) | | Specific Uses For Product | Car,Gun | | Surface Recommendation | Metal,Tile,Stone | | UPC | 768980080886 | | Unit Count | 32 Fluid Ounces | ## Product Details - **Brand:** Rust Kutter - **Item Form:** Spray - **Item Volume:** 32 Fluid Ounces - **Material Feature:** Spray - **Specific Uses For Product:** Car,Gun ## Images ![Stops Rust and Converts Rust Spots to Leave A Primed Surface Ready to Paint, Professional Rust Repair Manufactured in USA – Sprayer Included - Image 1](https://m.media-amazon.com/images/I/61iSPMUHnkL.jpg) ![Stops Rust and Converts Rust Spots to Leave A Primed Surface Ready to Paint, Professional Rust Repair Manufactured in USA – Sprayer Included - Image 2](https://m.media-amazon.com/images/I/81FpCss4y9L.jpg) ![Stops Rust and Converts Rust Spots to Leave A Primed Surface Ready to Paint, Professional Rust Repair Manufactured in USA – Sprayer Included - Image 3](https://m.media-amazon.com/images/I/91+Yt+aCMLL.jpg) ![Stops Rust and Converts Rust Spots to Leave A Primed Surface Ready to Paint, Professional Rust Repair Manufactured in USA – Sprayer Included - Image 4](https://m.media-amazon.com/images/I/91QCBD3HYSL.jpg) ![Stops Rust and Converts Rust Spots to Leave A Primed Surface Ready to Paint, Professional Rust Repair Manufactured in USA – Sprayer Included - Image 5](https://m.media-amazon.com/images/I/81jRmd5c9+L.jpg) ## Questions & Answers **Q: Where can I use Rust Kutter?** A: Rust Kutter is for use on metal surfaces that have rusted, such as: car bodies, metal tools and outdoor equipment.
