Product Description

When applied to rusted surfaces, it resists/retards rust in chemical change on drying to a tough, hard surface ready for priming. Paint jobs will last longer after an application of OSPHO because subsequent paint coating securely attaches itself so that moisture and oxygen normally do not attack the metal. Water-thin, covers a larger area than paint and goes on easily. Equally effective for exterior or interior. Available in Case Quantity only.

This stuff is GREAT!!! I have been testing different products such as Rustoleum Gel, Evaporust, Etc. For the past year... I ran into this product by accident and saw some of the reviews here. I must say, without having to prep anything, this stuff works great! I have an F150, and if you know about cars, these things rust faster than the average vehicle (especially when you offroad...) I only used half of this bottle underneath the passenger side of the truck and it removed 80% of the HEAVY rust in 24 hours. I just bought the whole gallon and I will be sanding and spraying the whole frame of the truck. I do believe this product can get rid of 99.9% of the rust when doing the proper prep. Highly recommended! ALSO, PLEASE HAVE IN MIND... THIS STUFF HAS A STRONG SMELL, SO IF YOU HAVE ASTHMA OR OTHER RESPIRATORY ISSUES, PLEASE USE IT IN A WELL VENTILATED AREA AND WEAR LONG SLEEVES, GOGGLES, MASK, ETC. PROTECT YOUR DRIVEWAY ASWELL!

4.0 out of 5 stars Slower to react than Corroseal, and maybe less reactive too.
Reviewed in the United States on August 17, 2023
Have been using Corroseal rust converter for years but it is is hard to cover with a finish (paint) once applied, so I decided to try Ospho based on reviews. Ospho is generally effective and more economical than some of the other rust converters, and importantly can be readily painted over if item is properly prepped as directed.

However, as the title states. Ospho is slower to react than Corroseal, and maybe less reactive too. Several areas on my project (enamel painted ocean mist exposed outdoor furniture that had rust breaking through) still had some orange rust as the margins where the enamel paint was not as compromised. I am certain those areas were well coated with Ospho and allowed to dry 24-hours. Conversely, Corroseal immediately turns everything remotely rusty black, good and bad.
