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

Great stuff I used it on an old mower deck and it worked great. All the rust turned black.

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.

I get as much rust off as possible(small wire wheel on die grinder does great for corners) put ospho in a spray bottle and spray her down good if it still looks rusty hit it again and respray. This is the first time I sprayed anything over it. Wiped her down with brake clean and used barrier bond and also raptor liner(needed more). Also both of those worked great barrier bond is hard(was nervous at first it was rubbery and could scrape off with finger nail but it’s not)raptor liner is just a little bit harder and sprays a little better(used the regulator from the barrier bond kit because it does not come with one).

This stuff is amazing. Spray it on Rust and it dissolves the rust and puts a coating on the metal to keep it from rusting again. You can reapply again for very Rusty areas. After it dries you can paint over it. However you should use goggles/face mask and skin protection. Read the warming label on the package

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.

Great product , works as advertised !

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