I would not put Sailkote on the traveler tracks and cars. SailKote is so slick that the bearing will not roll and they will eventually get flat spots on them. I would recommend that you use McLube OneDrop since it is actually designed for bearings and works quite well.
I know all about the flat spotting problem because the previous owners of my Nacra 20 used Sailkote on the traveler bearings and I had to replace them.
I wasn't a big fan of putting anything on travler car bearings until I first used the "One Drop" product (Harken or McLube?). It works magic on recirculating bearings...and the company I work at has a proprietary dry conveyor lubricant (that is mineral oil based) that works really well and lasts longer than the one drop....I use it on traveler bearings and beach cat wheels.
