Yeah, I sprayed the track before I slid the sail (Rope) in, but I think I should have sprayed the sail as well. I also need a new outhaul line. That should do it.
I'd be concerned that the last slug would not be well enough reinforced for that sort of loose-footed use. (You'd have to keep the aft-most slug in the track or the leach would be too full/the boom would be too low).
