I am refreshing an old O'day Javelin. It has a jib furler (Harken) so the jib stays on the forestay when docked or moored between sailings - you don't use the jib halyard, the sail has a wire built into the luff , and the wire acts as a forestay, fastened to the roller at the stem. I think I should protect the jib from UV etc., especially as this is a replacement sail and is in very good condition. I have no experience with using a jib sock for this purpose - I have seen some stuff online and it looks like the most economical approach is a kit from sailrite, although they seem to require a bit more sewing skill than I have demonstrated in the past. I am just wondering what others have experienced with using a jib sock - any advice welcome.
