Ospho Metal Treatment Gallon 2PK- Rust Converter for Metal Surfaces - Rust Remover for Cars, Boats, Trucks - Compatible with Most Vehicle Paints - Suitable for Indoor Use - Bonus Cleaning Towel

Took apart my dana 44 front end and needle scaler to all the rust scale.Then used a wire wheel on the angle grinder to clean up some more.I applied 2 coats of Oshpo using a paint brush with 24 hours in between coats.Then washed everything with dish soap amd a powerwasher.It did an amazing job of converting all of the orange rust into a black phosphorus. Left a white residue too.Came out absolutely perfect destroyed every bit of rust on the parts.I finished my job with 2 coats of rustoleum black and feel very confident that all the rust is completely gone.I will be using this product only for the rest of my life whenever I'm trying to clean up rust.

I forgot how good this stuff worked haven't used it since I stopped fishing and using it on the boats for fittings and parts on the crab debit Rush streets on the deck this is just a quality product

good sell

Converted light rust before i primed my trailer.

I have used it before so I knew how it worked. What I didn't like was the bottle had about 2 inches of liquid missing, compared to the picture. That was disappointing.

great deal

Good product

I read the reviews and thought maybe the negative one's were not for this product, maybe they did the coating wrong or just had a bad batch... so I bought a gallon hoping it would work good for me.It not only did not work for me, it was really hard to get the chalky stuff off to coat the metal parts with something else.This stuff turns white, and makes a mess out of the parts I applied it to.Don't waste your time or money on it!The first gallon I ordered never came, Amazon gave me a refund.. ordered it again this time it came, but it was a day or two late.Read the return policy before you make a costly mistake like I did!
