Hi Chris - Clark Rubber might have something. I was in a similar situation with finishing off a dew shield for a 100mm refractor. I initially thought of using some rubber edging to glue on but ended up buying the car edging strip. There are various sizes so it can come in fairly small profiles. It readily bends (around 120mm diameter for my scope) and there is no need of glue. It's also been very robust. Otherwise, as I said, you will probably find something else suitable at Clark Rubber.
