I have 2 cans, so what I have will likely last me the rest of my life. Amazon has over 2,000 cans in stock, but it looks like they will be building their retirement funds from it. Butchers Wax was the other brand that I have used in the past. I would think that Bowling Alley Wax would be good too, but I have never checked the ingredients to be certain that it DOES NOT CONTAIN any Silicone, which is the main reason to avoid other waxes. Automotive waxes always seem to have Silicone in them, and should be avoided.
Before you buy any wax to use in your woodshop, be certain, by reading the ingredients that there is NO SILICONE in it. Why ? Because Silicone will cause fisheyes in any finish that you try to apply to your project, if it has any silicone spots on it. By then, it's too late to fix easily. Anything containing Silicone was banned from my woodshop 30+ years ago, after a wax spray was used that contained Silicone. It was a nightmare to fix, and I ended up burning a lot of good wood to be sure that I would never try to build anything from it. Silicone is invisible, until you try to put finish over it. Automotive waxes are stored in my garage and over 200' from my woodshop.
