This product is recommended by Wills Wing for use on your keel (to make it easier to haul back the cross bars with your VG) and on your battens to put them in easier.

Sailkote is typically five times as effective, and lasts much longer than, wax, oil or Teflon® based lubricants.

Sailkote is the easy to apply high-tech, high performance dry lubricant that makes sails, hulls, rigging, deck hardware, and anything that moves on your boat run smoother, work more efficiently and last longer than you ever thought possible.

We tried generic Teflon spray but it doesn't seem to work as well as Sailkote.
