Update 12/31 Garage time spent wisely with the passenger door, cleaned all the rusted areas and POR15 the frame. When the POR15 dries I'll put a coat of POR black on the frame and tackle the skin later this weekend. I haven't done a skin before so .... this is new to me.
I need to do the same with the back side of dash that has the same level of rust, that will be next on my to do list.
Rusted areas POR15'd
Better than new!
