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

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.

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!

First, the actual product itself works great. I sprayed it on a few rusted areas on our car, and the light surface rust vanished and the heavier rust turned black.A few weeks later, I went to try it on another vehicle's rust, and nothing was coming out of the sprayer. After a few more minutes of pumping, the liquid started pouring out of the side of the sprayer, all over my hand and arm (FYI, this stuff BURNS when it gets on your skin). I washed off the sprayer, and removed the cover to discover that part of the sprayer tube had snapped (see pics). This is a very bad design because when ever you rotate the on/off end, it puts stress on the long "tube" part that connects to the main "pump" part. Also, when you pull the pump trigger, it also puts stress at the same point. The result, the plastic snaps at the weak point.I thought I could maybe super glue the pieces back together, but super glue won't bond to the plastic, at all. So, I now need to find a new spray bottle that the product won't eat through, or a new sprayer top that fits the original bottle.

Majic ?not quite but almost ! This is great stuff, removes rust like crazy.

I restore old cars, and I am cash-poor at the moment so I ordered this product hoping it might work enough. I was wrong, it works GREAT! Hint: wash off area, spray this on dry area, and let sit for 24 hours. WOW. What was a cheap tide-me-over purchase is wonderful!Now I'm ordering a second bottle, walking all over the yard spritzing screws and hinges and anything else that looks remotely rusty.HIGHLY recommend.

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.

Also works great for lime and calcium stains around the house. This has the same mild acid that the hard water stain removers at the grocery stores have but, It's way stronger. My wife was having trouble with hard water stains on our kitchen and bathroom sinks. Due to it's smell I figured this product contained Phosphoric acid. (don't quote me on this). So I gave it a try one day. Man doe's it work great. Let it soak for a bit till the bubbling stops, then clean with an old tooth brush or equivalent. reapply if necessary. Also use rubber gloves and eye protection as stated on the product label. As a side note: Rust Kutter if you read this you should consider relabeling a version of this for the kitchen and bath isle. You would blow the other brands out of the water.....

Used on my badly rusted garage door and it worked great. After years no signs of rust returning. Be careful to follow the directions carefully. If you do you will be pleased with the results! Would use this product again. Worth every penny
