I just bought a rear bench seat for my 67 chevelle. I got it for $100 bucks and it is pretty solid with no tears in the vinyl, only thing is the springs/cage under are rusty. They are still structurally good just brown from rust. What is some advice on cleaning them up, or is it even worth it??

well ive decided to just leave them the way they are. they are out of sight anyways.

I'd leave it myself............thier all a little rusty
