Ospho Metal Treatment Gallon - Rust Converter for Metal Surfaces - Rust Remover for Cars, Boats, Trucks, 1 Gallon

I used Ospho Metal Treatment while restoring and treating rust spots on my Jeep Wrangler, and I was very impressed with the results. After years of off-roading, winter driving, and exposure to mud and road salt, I had surface rust developing on several metal components. Ospho helped stop the rust and prep the metal for primer and paint much better than sanding alone. It was easy to apply with a brush, and I could actually see the chemical reaction working as it converted the rusted areas. Once dry, the surface was much more stable and ready for repainting. I used it on skid plates, brackets, and other underbody areas with excellent results. A gallon goes a long way, especially if you’re working on a full Jeep restoration or maintenance project. If you’re trying to save rusty Jeep parts instead of replacing them, this product is definitely worth having in your garage. It made my rust repair process much easier and helped me get professional-looking results at home.

Works great mixed it 50/50 with water put it in a spray bottle used it on my truck fram and car trailer took rust right off

Repair rust easily! Ospho is the permanent solution for any rust. Clean it, sand any particles away, follow the instructions on the back and it works! Uses: my lawn mower, snow blower, any rust in the vehicles, or any rust anywhere. After treatment, let dry, then paint. Done! Inhibiting the metal and killing rust dead. Great product!

This stuff is AWESOME. It really does eat rust. And it doesn't come back!

Ospho Metal Treatment does a good job preventing rust and treating metal surfaces. After applying it, the metal seemed well-protected and ready for painting or finishing. I appreciate that it’s effective and works as advertised. My only small complaint is that the application can be a bit tricky—it’s a thin liquid, so it drips easily and requires careful handling. Overall, it’s a solid product and I’d recommend it, just be prepared to take your time during application.

I have used Ospho on equipment, motorcycles, cars, trucks, trailers, new metals, old metals, and I have never ever had a problem with flash rust. Never have had adhesion or paintability problems with primers or paints using Ospho. Used epoxies and polyester primers never had a problem. Sprayed or brushed rustoleum or industrial oil base over treated Ospho never had a problem. Applied to sanded finishes that were washed, cleaned with wax and grease remover. Applied primer and or paint and those finishes lasted just fine. Applied body fillers over Ospho never had any problems. Get everything clean, de greased, washed apply ospho as instructed, prime, paint, and you will have a beautiful durable finish that will last a very long time. Ospho is #1 and a gallon will cover a lot. I brush or rub it on with a rag I do not spray it on. Wipe on wipe off it removes oxidation and dirt from paint. I could write a novel on my adventures with ospho over the years so could my father. Try some Ospho I dare you.

I have bought other brands and types of this sort of product and this one by far is the best. Does what it says.

MAGIC!! I’ve got a couple older cars that Rust, so twice a year I just park them over dirt and spray this stuff everywhere, especially up underneath lips and in hard to reach areas. The best way to do this would be to use compressed air and a parts sprayer. This will take surface rust and literally turn it black and stop it. Do it twice a year, and you do not have new rust happening. Do not do this over concrete though! It will eat your concrete up

Excellent!
