Its good stuff, and it seems to really hold up well. I typically do a small maintenence type wax before every trip, the stuff is so cheap why not? I have the big block though but i dont use that much per wax, then again i do only have a 151.
Its great stuff, definately as good or better than the OBJ F1 i bought with the kit..and waaaay cheaper. I mean it ends up costing you like 1.25 per wax assuming you use a whole 1oz every time...way better than the 12 or whatever all the sports stores here charge.
