Has anyone had any experience repairing a rusted frame? I recently noticed that my 94 sahara has rusted through around the right rear shackle. I live in Indiana so the winters bring the rust. I am wanting to cut out the bad spot and fabricate a repair panel. I know that I should go with a different frame, but I was looking for a easy fix. Just wanted to know if any other mid-west jeepers have been through this.
