I have can of paste wax (I think it's Minwax though and a can of Briwax). I used it a bit for furniture to get a bit of the luster back, but that was a good 6 years ago. Sounds like you guys are using it more for metal?
Honestly, paste wax doesn't do much of anything as far as a wood finish protection. Sure, it will fill in little scratches and nicks, but that's about it. I haven't done much woodworking lately, but even if I did, I don't see the huge need for it. You always just make your own stuff if you had to.
