Lubrication for Outhaul Track

[KZW]

For those 310 owners with Charleston Spar in mast furling: Do you lubricate the outhaul track on the boom? If so, with what?

My furler rotates reasonably well, but the car on the boom track seems to have a good bit of friction.

I use Sailcoat spray lubricant to lube the outhaul track as well as all the turning blocks and car.
Definitely notice a difference in the ease of unfurling & furling.
