There are endless threads on waxing chains, including another on the mechanics forum right now.

And while most of that Aussie fellow's tips are good, some of us cringe at his videos because of his disregard for safe handling of gasoline. Note the open containers on a workbench near electrical outlets and devices capable of producing sparks. As a former OSHA inspector I've already seen the consequences of such disregard for the dangers of flammable liquids.

So don't do that.

But otherwise, sure, wax has some benefits. And some drawbacks. It's best for dry dusty regions. It doesn't last long between applications. And purists may be annoyed by the more audible drivetrain noise, even when the wax is indeed working properly.

I use it because my bikes are in my living room and spare bedroom. I got tired of chain tattoos on my legs, pants and cats.

And I still have one bike with a conventionally oiled chain, my all weather errand bike. Park CL-1 lasts longer between applications and doesn't wash out in rain.
