Don't know how Black Jack #57 compares pricewise (a 5 gal bucket is around $50) but that's another painted-on option to consider that will seal seams and waterproof pretty well. Downside is there's some temperature/humidity restrictions during application.
Don't know how well it would take to having sand raked over it daily but I've used a metal rake and shovel on mine and so far it still looks good.
