Tessa loom tape is good for the tambour roof guides.

Velcro self adhesive tape, simply use the soft part cut a few small pieces and stick them into the tambour channel at several places toward the rear(close to the upper bed ) to increase friction.

Agree with Loz also loom tape will also work

I extended the exisiting felt tape up to the front of the sliders. Some very, very thin felt tape. And some thicker on the tambour front to stop the rattling.
