Am looking for an adhesive to reglue small portions of my rubber roof after I raise it and replace the plywood underlayment. Most people I've contacted recommend Dicor 901BA, but I'm hoping to find something in a smaller quantity, available in a well-stocked hardware or home improvement store. From what I understand, one must be careful not to use solvent-based glues that will attack the rubber. I've already had one good suggestion that I might get an RV service place to pour a small amount of an opened 901 container into one of mine, but was hoping for something that will not "go bad" for a long period. Can anyone out there help?
