Don't know but I used to have a roll of teflon tape I used to use for all sorts of slidey purposes. Its used on plastic sealing parts of heat shrink machines. We used it often, just stick a stripe to the rubber base of the sealer, the sealer head presses down with its heated wire to cut and seal plastic around a product which goes into the heat tunnel for shrinking. The teflon tape doesn't burn and the melted plastic just wipes off to keep a clean sealing edge. Pretty sure we got it from 3M and it was about and inch wide, but I've seen it in other sizes. it's like a roll of masking tape except it had peal-off backing to stick it where you need after cutting a length to match. No idea where mine has ended up but its surprisingly useful for all sorts of things.
Edit: It was more like a giant roll of masking tape or bandage. The stuff we used was clothe tape with the teflon layer on top to it had a little thickness to it and the full roll was like a dinner plate in size and the flesh colour of bandage. Looked on bunnnings and they didnt appear to have anything similiar only teflon plumbing tape which is nothing like this stuff.

PROVIDE! . Thats the sort of stuff I was using. made great feet for computer mice to glide on my desk with ease. You should be able to adapt someting like this for your dob (a wider roll probably but the link gives you info for local searching).
