Has anyone tried going over the top of the existing roof with cargo trailer roof sheeting? Thinking the adhesive strips may hold it up enough above the existing rivets where it will not matter. I see that you can buy the radius edge and corners as well. The ol girl is pretty eat up and not really wanting to cut all the rivets out and pull the old off and by time I do surgery and cut out all the holes and weld in patches to spray on roofing it will be summer time again.
