Please note that I'm not choosing one over the other. I intend on coating all rust with Ospho.
Here's my question...is there much of a point to the Rusto rattle cans? It "paints" everything black so I guess I can't really tell if the rust underneath is being reformed.
Going forward, I intend on using the cans for light surface rust in the sheet metal panels and what not since I already bought them but can I trust it more than that? Does anyone like the stuff? Can I use it as an underbody coat for those hard to reach places after I've let the Ospho do it's thing?
The cans aren't the magic stuff in the jugs. They're totally different despite having the same name.
Its probably good after the ospho does its thing. I've used it before but only after actually treating the rust.
