sorry to hear that. Mine has some cracking as well and had 2 cracks right through above the rear window( I patched from the outside). I think the snow load on the roof stresses the glass. I also had leaking from the rivits on the
awning rail. I coated the entire roof area and the top 8" or so with White Knight Flex Coat and it sealed very well. I am thinking about doing the entire top half with it if I can get it to go one smoother with a closed cell roller. It sure did cover the spider cracks. I think I will strip the interior this
fall and repair the
fiberglass from inside and may add some carbon fiber tow around the
windows. It will do for what we want it for. Tonight is wiring night, time to put a 7 pole connector on it so I can get the
brakes working again.
