Joe...You are right...a cat walk would make it much easier to work on the roof. I liked the idea of smoothing out the metal around the sunroof hole so I wouldn't have to fill up the channels with putty/caulk but this is taking a while trying to re-create the ends of the channels to be rounded out to look factory.
I am "almost" there....a little more filling and sanding and then primer and then I can install the rear sunroof.
