My brother works for the Xtrak company in Florida. They bought the wax from another company in Cali i think. He gave me about 15 bars of various temps. Works great and usually stays on for more than one session. You do have to use the right temp though.
I like Sticky Bumps - seems to give the best grip and last longer. Somebody mentioned basecoat. Once I started using it I saw it made a difference with wax being evenly spread and made top coats last longer. I strip my boards a couple of times a year. It's nice to have a fresh coat and also check for cracks.
