Metal turns into rust, then into thin air...

Today I removed the floor patch under the driver-side floor. It's not a good feeling to find yet more holy metal, but it has to be done...

And while I was down there I noticed a hole around one of the rear spring hangers. I'm just going to ignore it for the moment as I've got enough on my plate to think about at the minute with the crossmember, chassis legs and the holes in the floor. Here you can see how bad the nearside chassis leg is by the light coming up through the floor...
