So I expecting to find problems ... what I found on the roof with no rust whatsoever...(that brown is primer) thought the tail panel was going to be screwed ...what I found was instead of pulling out a few dents with a stud gun someone just put brondo over the low points (1/4" thick is a few spots) so great news overall no rust no need to replace tail pan... will hit it with 36 grit before I ship it to a body shop
