i would use a adhesive caulking sold in any hardware store not sure the plastic will adhere to the silicone for very long. you could also use a double sided tape which might actually be the best get a good quality brand like 3M and narrow like 1/4 in wide should be able to make most of the bends with no breaks.
disclaimer no experience with this just what i would do.
