I've got a shelterlogic temporary garage that I definitely have gotten my money worth but am trying to stretch through winter. Its the tarp kind over a metal frame. wearing through at metal frame angles and looks like a tarp with strands . Its the same price as the whole unit to get a replacement cover so I don't want to do that. And its just a pain to put up. Thinking of putting a backer like rubber roofing or thin foam on the inside and coating the wear on the outside with something. will fiberglass resin burn/melt it? Trying to avoid the ugly just putting a tarp over it for now and metal roofing is same price as a whole unit. ideas?
