Oh, thanks for posting Rick.

I used the brushed-on Hammered gray on some steel in my garage and I did it with NO prep. This was big I beams that were already primed. I literally dusted them off and rolled it on. That stuff is HAARD when it dries thoroughly. Just cause the little foam roller was loaded, I put some on my exposed truck frame. Again, it had light surface rust and I just took a dry rag and wiped it off. I rolled a couple areas one coat only and it has been in the DIRECT sun for months, exposed to rain, etc - looks great, no rust coming through. I'm very impressed with that stuff. I don't know if the rattle can stuff is as good but the brush on stuff is great.
