First: I bought this Ospho with my own money and I am not being tortured to write this.As you know painting over sanded rust doesn't work for very long. I've used various rust "converters", and I like Ospho best so far. Just scrape off loose rust first. Try a "flap disk" on really thick rust. Then slop on the Ospho and leave it overnight. I keep a supply of cut-off plastic bottle bottoms for this step and painting in general, so I don't contaminate the supply bottle. If it doesn't look rust free, I do it a second treatment. Usually the first treatment is fine. Either way, it goes really fast. I use cheap "chip" brushes, work outside because it's going to drip. Don't get it on your clothes because it's an acid. I like using a brush because it mechanically pushes whatever I am using into the surface better than spraying or rolling. I spray off the surface with a hose, let that dry and then prime and paint.I work on a lot of different things and use a lot of different products, and find it useful to read reviews before I try something new. I'm mystified by the usually small number of one star complainers and wonder if they read the directions, actually plugged the device in, put good gas in it, shook the container first, stirred, etc. You don't have to shake, stir or pull start Ospho. I have never had any issues with Ospho containers. I hope you don't either. This is good stuff, easy to use. It works.
