Well I got the passenger side cleaned up and my initial 2 coats of Chassis Saver on the floor. I think I may need to coat a little more, I didn't get it spotless or anything, just the major stuff off, pin holes welded shut, ground flush. It's getting a layer of Dynamat type stuff anyway, so no one will ever see it.
I was really concerned with the area in that channel, there was a fair amount of rust in there, but my little siphon feed blaster got it out.
