Rust has now been addressed on the passenger's rear quarter, in the trunk and across the back of the car. Recently repaired driver's rear fender dogleg and front door. It was just a 3" x 4" patch but it warped the driver's door and as I tried to repair it it just kept getting worse and worked up into the top of the door. I finally just cut it out and welded in a large patch. Today I finished the doglegs in both front fenders. I think all the rust is gone. Now, I'll continue to strip the old paint and get it in epoxy.
