You can order cactus juice off of his website. buy 4 gallons for about $280 including shipping.
I have used cactus juice, stickfast, and ultraseal. The bvv stuff in the blue jug is likely ultraseal but can't say for sure.
Of all, I liked the ultraseal the most and the stickfast the least, but they all worked well. I quit using the ultraseal mostly because the salesman was a dick! … and I had to order $4000 at a time to get it at a decent price.
I'm currently using cactus juice but am always open to new options.
