gorilla glue did not hold up. lasted about 2 top down cycles and came off. i then tried black silicone type caulking and that has held up now for about 5 months. but i still do not thnk this is the proper repair. so i'm going to be removing the top and repairing a frame section that tore the top and then while the top is off the car see if i can sew the valance back on just under the window and then just use that glue i seen on a youtube called stormsure. unless 3m returns my inquire on a repair using there products like the factory used. i may not be able to give an update as the car is for sale now and my guess is after i repair it and sell it the owner will never tell me if it worked.
