I had tried one of those wax dip long time ago. Not worth another try. It has very short service life, within a couple of days chain start making noise as if it has no lubricant. It's still better than white Lightning which lasts only an hour so of riding.
My take is that because wax is solid at normal temperature, when it strips off the surface of the metal, no wax will fill in between the metal unlike liquid lubricant. If anybody believes the wax would be absorbed by the metal as the instruction says, they are living in the dream land.
Too much work for no result. I would doubt that anybody use it regularly.
