OK buddy...
Candle wax will make your skis ski worse.
With ski wax, you apply it, then scrape as much as you possibly can off, so all that is left is the wax that was absorbed into the porous base material.
If you cover your base with candle wax, you pretty much just cover the base, because candle wax isnt designed to be absorbed in the same way flourocarbon, and even the most lame hydrocarbon ski wax is designed to.
