That’s a prime spot for one of the dry lube products.  I like the ones with teflon best.  Graphite would also work, but I don’t know how long it would past.

Probably a good solution.  I have a spray can, probably Blaster Teflon, but it is too soft to last.  In the past I have used Slip Plate Dry Graphite Spray which was very hard & durable, so much so that in aerosol form it was like paint.  Very difficult to remove any overspray.
