Lubricating mast track
I used something called Fastrac. There are 2 parts, a little metal slide that you put a cloth sleeve on to clean the track, and the lube. It works amazingly well after application. I can haul the main on my Tartan 37 without the winch. You have to run the slide up and down the track to clean it,, then change the cloth sleeve and apply the lube. Make sure you have a good downhaul on the cleaner!
