Virtually rust free floors
Some mental notes about my flooring:
I spent about eight hours total grinding in applying a first coat of Ospho over the course of a week. The floor has this white film on it from whatever they etched it with originally I guess. Almost all of my surface rust was on top of that. It pretty much just chipped away to bare metal.
Most of the bad stuff wasn't too deep. I was worried about all the rust at the back wall but I ground it down there and I think the rust converter will do its job. There's a bunch of rust under the two back windows so I can't wait to see what that looks like when I take those panels off.
The directions on the Ospho don't say anything about neutralizing it before primer. But that's what everybody does. So I guess that's what I'll be doing.
There's three spots with holes to the outside. Two of them closing up together it's probably one patch. I don't think I'm going to be patching for a couple of months. So I ground them down as best I could and applied the Ospho. If I hadn't already seen the underneath of the bus I would think I was done. But I'm going to have to get under there still and cutaway some rust. Probably end up with bigger patches when I do that. So I figured I would try to convert and seal what I could until I got underneath.
It would be nice to start taking things off the walls without all the rust and dust and mess.
