Quality Chemical Oxy-Gone Rust Remover and Metal Treatment/Rust Repair/Prepares surfaces for painting / 1 gallon (128 oz.)

This is an excellent product that works exactly as advertised. I used it to remove rust from metal parts, and the results were impressive. It cleaned the rust quickly with very little effort and left the surface looking much better. The product is easy to use, and a little goes a long way. If you're restoring tools, automotive parts, or other metal items, this rust remover is definitely worth it. I would buy it again and highly recommend it.

This product is really amazing. Used it on the undercarriage of a 1992 Ford 2500 pickup truck 4x4 that had substantial rust with rust flaking off the frame, tapped frame with hammer to knock off any real lose rust, then power washed at car wash, to remove any dirt and any more rust that would fall off(no grinding or wire brush there was still spots on frame where I could have brushed or power grinder off rust. But whole purpose i bought product was to avoid hours of brushing or power grind, and save time. Man did I.) before applying. I let undercarriage completely dry. Grabbed a standard spray bottle filled it up with product (I didn't dilute but believe it said you could for light rust.) and sprayed on with spray bottle. You could see it go to work instantly!, I sprayed the whole undercarriage it took a gallon to do this and let dry for 48 hours(I drove truck around during 48 hours) it turned what ever rust was on that undercarriage and literally bonded it back to the to the metal making a hard paintable surface. It wasn't smooth, but it wasn't rust anymore either. Paint sticks to it well as it sets as a primer. If you have a used vehicle your thinking of undercoating even if you don't have rust. I would still spray this product on to insure the under coat does not trap rust in. It saved me days of brushing and grinding! Had it all done in one day and painted 48 hours later in one day. It is a fantastic product! Easy to use and apply, and dose what it says even on heavy rust. I would wear protective gear, long sleeve shirt you can throw away, eye/face, and hand protection protection. It does sting a little if you get on skin or in eyes, but not extremely. It has almost no smell or fumes, and is water based so it rinsed right of my skin. I would definitely purchase again . I gave five Stars, because of ease of use and application, and dose do what it says it does even on thick rust. Over all good product.

Used this to help keep flash rust to a minimum while blasting a chassis It does work, it does to a degree convert thin rust deposit. Does not dissolve or remove rust scale Heavy rust must be removed mechanically, this will keep bare metal relatively rust free until epoxy or paint coated... Photos are after wet sandblast, frame immediately flash rusted, this stuff cleared it and kept it clear

I just used this on a restoration project, cleaned off the flakey rust with a wire wheel and then brushed this product on. After sitting overnight I had a nicely sealed surface to scuff and paint over. I can not speak to the longevity of the sealing properties as I just completed this repair.

Extremely corrosive

Did exactly as described work amazing on my trailer

So far so good. Lot of white haze, but can be mitigated with a good brush and waiting till it's almost dry and "brushing" out the white.

Excellent product, did exactly what it said it does, I had a heavily rusted bridge support I scraped off the loose rust and wire brushed everything and used a spray bottle to apply worked wonders
