Any use ?

I know the kind of thing you're after, however I've got no idea what it's official name is, let alone where you can buy it.

A bigger rubber version is often used on roller/shutter doors, but the thinner harder plastic version is fitted to some 2 post car lifts.

Yes, flexibility is the key, so it will mould/seal itself around the moving bits. I've used slider potentiometers/faders on audio and lighting control desks in the past that have had a thinner version of this stuff covering the actuator slots but it came as part of the unit from the Far East.
