32fire is right, but I would have it sandblasted, and shoot a couple of coats of Epoxy primer on it right away. You can do you body work on top of the Epoxy with no problems. That way if you can't work on it right away, it won't rust.
Most of the time, I will epoxy prime the bare metal and let it set for a few hours. Then I apply a couple of coats of 2K primer.
Reason for this is.... If you wait past the recoat window for the epoxy, you have to sand it before you can apply the 2K for blocking. Epoxy is hard to sand, but 2K is easy.
You can apply your filler on top of the 2K and take your time getting the body straight.
After you get your bodywork done, then apply 2 more coats of 2K over everything and block sand. Repeat this process until you have the body straight.
Then you can apply 2 coats of reduced epoxy for a seal coat and apply your basecoat of paint.
