Stick a fork in it, 'cause the rear suspension is DONE DONE DONE!
We cleaned up the loose rust on the back half and I painted it with Rust Seal. I love that stuff. It goes on white, but reacts with the rust and turns it to *hard* black primer. We used this stuff on the grousers on the tracks of Brian's snowcat years ago, wonderful stuff. Expensive at $40 a pint, but so worth it. It does turn the bare steel to a yellowish/rusty color, but I am really liking the rustic look it gave this crossmember.
So good to get that part done though!
