I have a similar thing with my rig, across the back there is a fiberglass quarter round panel from the roof to a flat filon panel, just below the escape window is a seam, covered by a "C" channel and another filon panel down to the bottom of the rig. The two filon panels are on an angle, the top piece goes out slightly from wher it meets the round top piece and the bottom goes back in to the bottom. I want to remove the "C" channel and glass over the two filon pieces and then reinstall the "C" channel. I was thinking of using a six inch wide matt, three inches on each side of the seam and two four inch matts overlapping over the seam. Using fiberglass matt rather than cloth would be two or three times a thick as the filon and yet hardly noticeable.
A mobil repair guy said to much flex but the whole frame is welded steel and seems pretty strong. I guess the side to side motion would cause some flex but right now the seam is taped and looks like shoot. So how much flex is there on the rear cap and would a good glass job help seal the seam?
