This product really works if you follow directions and 24 hours use a good brand spray paint over it to seal out moisture. I Use it on rust on truck frame to slow and stop rust. works as described. remove all loose rust then spray Rust reformed wait 24 hours top coat with black spray paint. Usually keeps rust from spreading. I touch up areas that do rust through after a year or so but it really does minimize its growth. 5 cans usually will cover average frame. Use a good mask save you lungs. **********UPDATE March 2017*************** I have used this product on other rusted chassis past few years........ If you follow instruction spray rust wait 24 hrs then over paint. After a year my truck which I sprayed last March.and using it all winter. No rust has come through my truck, a few little chips but thats it. It remains solid black and rust free. This spring I will power wash chassis touch up any small areas and repaint the chassis again to insure it remains that way. If air cant get to treated rust it cant start again. I also did my daughters car 2 years ago which had a lot of surface rust when she bought it used. I did same thing and now after 2 winters and me not retreating it, I was surprised to see after 2 winters only some rust has come through but nothing compared to what shape it was in. I use this product every spring to keep my older cars that drive in an area that salts the roads in the winter frequently and for the hour or so it takes me to recoat and repaint and the 35.00 it costs me between this product and GOOD BRAND black spray paint to top coat. To keep rust at bay. Its well worth it +++++++++Sept 2018=== still holds out keeping rust away. I just ordered another 6 cans to do a 05 Mercury Mariner. I just bough I have the start of very Minimal surface rust so I brushed and with air pressure to blow clean. Took off each wheel all exposed metal then down under rocker panels rear wheels. Tomorrow I will top coat with paint. Its a lot of work but once it covered I know it works. I do power wash road salt on my trucks and cars coming in after a snow and they are garage kept. I do get very minimal specs of rust that will appear after a long winter. I just hit them quick then respray with paint. But nothing compared to the whole chassis .If you car fully over taken with deep rust this may slow it but the cancer has set in deep when its that bad.
