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

  • Useful, works.
It works. I sprayed it on, it started reacting to the rust, and you can wipe it off. I used this on screws that had rusted on my car and it just bubbled it away lol. Then I wiped it down and it was relatively clean. I left it to dry which it does say can take up to 3 days. I wish it were quicker than that but doesn't look like it. I plan to wipe it down some more and then use my screws. Anyways, the bottle is good, and the sprayer is nice. I wish it didn't make such a mess when spraying upside down when laying under a car on a garage floor. Overall, I think this will be useful for tackling rust. I HATE RUST ... show more

  • Best product of its type that I've found (and I'm really old)
Have tried quite a few products of this nature over the years. Most do a good job of locking down the rust with the chemical conversions that they do. This one does the best and most efficient job on a used vehicle that I've found. The "Spray" and "Stream" settings on the twistable nozzle worked perfectly when I did my '09 Tacoma a year ago, and again when I squirted some on some rust areas on my baseboard radiators. ... show more

  • works good but be careful
DON'T GET ON PAINT!!!! Does a good job on rust but don't get it on any surface that you don't want to get messed up, especially paint. The directions are not nearly clear enough about this - it should say will wreck paint, not dull or slightly discolor. Customer support is poor

  • Did more than I thought
This stuff is amazing. Just be warned, if there is rust under the crappy and non primed paint job your builders did, the paint will flare up too. Like a really good paint stripper. Made my job easier. Some medium grit sandpaper and the paint and former rust were gone. After is with rust stop paint/primmer. ... show more

  • Rust Treatment Worked, Paint not so well
Nice easy application. I used spray and brush on a very rusted snow blower. It converted the rust but also peeled an existing cheap paint job at the wire brush marks and along bare edges of the paint. Needed 2-3 applications due to the amount of rust so I ended up having to chase peeling and blistering paint. Had to finally call it good but had no intention of chasing so much bare metal. Be careful with a wire brush on nearby paint. You have to be patient with applying, rinsing and drying. ... show more

  • Worked great on my car.
I recently used Rust Kutter to tackle a rust spot on my car, and I am extremely impressed with the results! This product worked exactly as advertised. The rust Kutter not only effectively stopped the rust from spreading but also converted the damaged area into a surface that was ready for painting. The application was straightforward, and I appreciated how quickly it began working. Within no time, I could see a noticeable difference—what was once an unsightly rust spot was transformed into a clean, primed surface. It left me with great confidence to proceed with the painting, knowing that the underlying damage was addressed properly. I highly recommend Rust Kutter for anyone dealing with rust issues. It’s an effective solution that saved me time and money on more extensive repairs. If you’re looking to restore or maintain your vehicle, this product is a must-have in your toolkit! ... show more

  • It's Good!
This stuff really works and no damage either even on a fabric after I purposely tried to see what happened on carpet. It totally desolved the rust and left it looking like bare metal with a clear coating. I don't know how long it lasts and I have no intention of painting anything so maybe it will need another treatment someday. ... show more
