Try it! I do it once/300-400 mi and at this point it takes me under 5 minutes to break, dip, wipe and re-install a chain. Plus the 20-30 min elapsed time when it's just sitting in the melted wax.

You need to make sure that everything is super clean off the bat so there are some barrier to entry tasks associated with cleaning the rings, cassettes, pulley wheels and degreasing the factory lube off a new chain. Plus you need a dedicated crock pot so that's another ~20 bucks. Bulk candle wax on ebay is very cheap and can be re-used for more than a few chains so it's not really a significant cost.

At this point I spend about the same amount of time maintaining my chains as I used to with wet lube, and I have a clean, silent drivetrain that I get to ignore for weeks at a time. It's supposed to be lower rolling resistance too but that can't make a big difference
