I use a "special" was made from Johnson's. Harder'n a rock and almost bulletproof. When you finally find Johnson's wax, do this: (all measuring by volume)
1/3 Johnsons wax 1/3 Carnuba flakes 1/3 Pure beeswaxMelt slowly in an old aluminum coffeepot (thriftstore $1.00) on a hotplate OUTSIDE!! When melted together, remove from heat and blend in enough pure turpentine to make a paste again. (I often do the melting/hardening thing several times til I get the consistency I want.) What you're looking for is a barely workable paste--(hard) This stuff goes on stiff and needs to be buffed out almost immediately. You can give yourself more time by adding more turp. Once you get this stuff rubbed in everywhere--miter slot, extension wings, fence rails. table top and fence surfaces, you'll have a very slippery, HARD surface that will not give you finishing problems when you drag your wood across it. My CI Delta Contractor's saw sits outside year round for the past 3yrs--right now covered by 18" of snow (tarped) and the metal surfaces show no ill effects. Spring and Fall I strip with lacquer thinner and re-apply the wax, heating surfaces somewhat with a heat gun for initial light coat, then final protective coat. Holds up well between the 100plus to minus20 degree temp swings we have here in Montana.
