Review: It actually works - Wonderful product, does what it claims. Repairing the rust on my truck especially the underside using a sprayer bottle and a brush to spread it. First went with a scaper to remove loose rust and dirt and did two coats and now it's all black and water repellent. Will not coat the underside with anything else till possibly next year in case I need to do one more treatment as the rust was severe on some areas. I chose to treat it (converting) rather than remove it cause if there's any left, it will come back, it's like cancer. One gallon should be enough and have some left to do the steel rims, calipers, drums and other rusted parts Very grateful for this product, tried many other and this one actually works. Review: Revising a one-star review to a five-star review - I just spent 3 long days peeling a 20-year-old commercial bedliner spray job on my F-450. Part of it had come loose and the rust was starting to be too much to ignore. Peeling The remainder with hammer, chiselwith and half dozen wheels of paint and rust remover with a grinder. The job absolutely sucked as each morning the entire grinded area was all rusted over again. I use the product over the really bad rust pitted almost through areas and it did such a good job even on the exterior parts that was just bare metal I ended up laying this product over the entire bed before doing a new bedliner rolled over finish. The proof was instant as the next morning there were no rust anywhere. The product does say wait 48 hours and it confirmed the effectiveness against rain and morning dew. I was quoted $1800 to respray a bed liner after I did all the hard work so I ordered the herculiner kit. I like this product so much I went on to use it on top of a 2003 expedition roof and then use the same bedliner finish on top of that roof. I have been to multiple finishing shops charging me thousands of dollars to stop the rushed holes on the old Ford roof and All I did is waste my money with them. This product along with roofing fabric over the holes of rust and the bedliner finish renewed my SUV for another 5 years. Can't beat the naturally aspirated v8s that has been maintained so why you lose a vehicle over rust that now can be taken care of with this phenomenal product. I am now using this chemical in a spray bottle to go underneath my truck and spray the entire frame along with the drive shaft and anything else that looks rusty. Every 6 months I go under the truck with a can of rustoleum rust converter and it's gone within months. This product is for real not just surface garbage. I'm starting to use this as the primer coat on anything that has metal. ## Features - CONVERT RUST: Convert rust to an inert coating that seals out moisture to prevent further corrosion - SAFE TIME & MONEY: Eliminates the need for sandblasting, grinding or scraping - EFFICIENT: 1 Gallon Covers 500 square of smooth, nonporous surface – That‘s an entire Dumpster! - ULTIMATE PROTECTION: Convert toughest rust and corrosion caused by all types of weather conditions - MULTI-USE: Use for automobiles, machinery, railings, structures, tools, marine applications and more! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B014LR5PA2 | | Age Range Description | Adult | | Best Sellers Rank | #9,826 in Automotive ( See Top 100 in Automotive ) #55 in Care Corrosion & Rust Inhibitors | | Brand | FDC | | Brand Name | FDC | | Color | multi-color | | Color Code | #4A2C2A | | Container Type | Barrel | | Coverage | 500 | | Customer Reviews | 4.4 out of 5 stars 3,200 Reviews | | Dry Time In Hours | 0.33 | | Finish Type | Matte | | Full Cure Time | 48 hours | | Global Trade Identification Number | 00853908006120 | | Indoor Outdoor Usage | Outdoor | | Is Waterproof | False | | Item Form | Liquid | | Item Volume | 1 gallons | | Item Weight | 8 pounds | | Manufacturer | FDC | | Model Number | 13 | | Paint Type | Oil | | Part Number | 67427 | | Size | 128 Fl Oz (Pack of 1) | | Special Feature | Rust Resistant | | Special Features | Rust Resistant | | Surface Recommendation | Metal, Wood | | UPC | 853908006120 | | Unit Count | 128 Fluid Ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** FDC - **Color:** multi-color - **Finish Type:** Matte - **Indoor/Outdoor Usage:** Outdoor - **Item Volume:** 1 gallons - **Paint Type:** Oil - **Size:** 128 Fl Oz (Pack of 1) - **Special Feature:** Rust Resistant - **Surface Recommendation:** Metal, Wood - **Unit Count:** 128 Fluid Ounces ## Images ![- Rust Converter Ultra, Highly Effective Professional Grade Rust Repair Spray (1 Gallon) - Image 1](https://m.media-amazon.com/images/I/81Qh-mOqW4L.jpg) ## Questions & Answers **Q: How many square feet of coverage is expected with 1 gal? I have a scraped steel trailer bed with surface about 6 x 18 feet I want to coat, then paint.** A: I used 1/2 of the gallon on a 9x8 steel flatbed. 2 coats. Worked amazing. It converts whatever rust it touches to a back hard substance. If you have rust scale it soaks it up and turns hard. **Q: What is the shelf life of this product once opened?** A: There is a product called "End All Rust that I purchased in 2003 and just used it again this year 2023. A little clabber at the bottom of the jug, but it did a great job! Still working after 20 years. I can't see why this FDC wouldn't last at least half of those years. Rust converter is rust converter. **Q: Can I apply this to a wet surface?** A: It applies just fine on a wet surface, but you're diluting it. That said, as always, you would probably have better results on a prepped surface. **Q: If used on frame does it have to be painted?** A: No it doesn't. When cured, it will leave a black polymer finish that's fully sealed & waterproof. If you decide to paint it afterwards, use a high quality oil based paint. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It actually works *by G***N on August 11, 2026* Wonderful product, does what it claims.

I will give a review of my current experience. The shipping was quick and the product was at my house in just a few days. I am restoring a 47 Chevy truck and there is quite a bit of surface rust and pitting. I completely sanded the door down, took a wire wheel to the pitting and finally sandblasted. It came out really nice but there was still some dark color in the deeper pits. I painted this product on with a brush. Almost immediately it turned all of the metal it came in contact with to a dark purple. Once it dried, it was almost black. Give it a day and put on another coat. After a few days I took the DA sander and went over the whole panel again, only leaving the Rust Converter in the pits. I cleaned it all up and did my body filler over top of the RC. Sanded down really nice. At this point I have primed but nothing further. After a few weeks all looks good. I really think the RC is going to help deter the rust from coming back. It is also easily sandable by hand and comes out really smooth, ready to take primer directly on. I'm overall happy with this product so far. But in all honesty, it will need to be painted and in place for a few years before I know it is going to work as expected. Thanks. ## Frequently Bought Together - FDC Rust Converter Ultra, Highly Effective Professional Grade Rust Repair Spray (1 Gallon) - Rocaris 6 Pack Carbon Steel Wire Wheel and Pen Brush Set with 1/4-Inch Hex Shank for Rust Removal, Corrosion and Scrub Surfaces - Rust-Oleum 248657-6PK Stops Rust Undercoating Spray, 15 oz, Rubberized Black, 6 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/19340732-rust-converter-ultra-highly-effective-professional-grade-rust-repair-spray](https://www.desertcart.de/products/19340732-rust-converter-ultra-highly-effective-professional-grade-rust-repair-spray) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-10-03*
