Stops Rust and Converts Rust Spots to Leave A Primed Surface Ready to Paint, Professional Rust Repair Manufactured in USA – Sprayer Included

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

Works as advertised. Great product

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

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.

Kills rust on contact. Great product.

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.

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!

Worked great. Easy to use dried quickly. Put plastic down before use

wow this stuff works in seconds.

While this is expensive then it has done its job very well thus far. Have used it over few years and most of it is still left: you don't need much for smaller areas. Another funny thing is that it doesn't evaporate: even a tiny amount will remain in the container where you used it from. So remember to use up all of it or pour what's left back in the bottle.

Me gusta este producto mucho. 👍

Works as well as per my research before purchasing, can also be painted on the next day. Expensive but worth it overall.

One of the better ones ive used. Spendy tho. Watch YouTube on how to use acids on car panels correctly, otherwise you may aswell paint over the rust you're removing.
