I am recovering 2 old springer seats, one with double pans, one with only one. I did one before trying different adhesives, but ended up using a hot glue gun on the edges. Nothing else I tried had an instant bond. I have som 3M spray adhesive that is a medium hold, was afraid to try the high strength used for vinyl tops. What is the best adhesive to get a good, instant bond on the pan to the fabric that will hold. Thanks
