That's not what I've used. It comes in a squirt bottle like windex and it has an acid in it, along with other stuff. You wire brush and sand the rusted areas, then spray it on the bare metal. I've used it on railings and outdoor brackets for clients. The next day it has a bit of a sheet to it that you just paint over.
I looked on their website and didn't find it. I just tell them at the store what I want and that's what they sell me. I know there are others brands out there, that's just the one I have experience with.
I have used and still have some of the brush on kind, I suppose you could put it in a spray bottle as well.
