The previous owner/dealer had resealed the seams all around on the roof. Doesn't seem to be lasting. What's the best product to use, to do a proper job? I haven't found any cracks. I know there has been a leak at some point, because inside the wood shows signs of rot. See the attached pics of some of the areas in need of resealing. I see Rhino lining as a possibility, but not sure it's the proper method for this application. EDIT (2017 11 15): I added a pic of the full ??strap??, not sure what to call it. Does anyone know how far the screws go thru the roof? Do they go all the way thru to the wood fascia on the inside? The afore mentioned rotted wood needs to be replaced, so I'm wondering if those screws will create any problems removing that fascia. That may actually be how the inside fascia is held in place. ??
