There is a double sided tape developed by the evil military-industrial industry complex for the space program. I got a 1/2 inch wide 36 yard long roll from Tap Plastics for $7.95. This is the middle grade product of three grades. The top grade will not come off after 24 hours curing time. It is designed for flat surface bonding, not irregular or flexible (seat covers etc). I've used it to reattach the "O" on a 65 Mustang's hood "FORD", and the "I" on a HUNDAI as well as repairing trim.
Just another recomendation for your consideration.
