All the commercially produced silicone seal products that get attached to glass, aluminum,
fiberglass such as shower door seals are put on using VHB tape. But you do need to go to the 3M website and see
exactly which formula of VHB tape and what bonding primer (if any) is required to use it on silicone.
The 3M website might have other suggestions for bonding cured silicone to various substrates.
