I tried wax for a few weeks back in the 80s. I found that no matter how much care I took I still only got 100-200 miles before the bike started squeaking like a herd of poisoned mice. That meant I was rewaxing every two or three days, which got old fast. So my attitude since then has been that waxing works great if you don't ride the bike.
I also remember when White Lightning and the knockoffs were all the rage. I remember it specifically because there were several years in there when squeaky chains were considered the norm.
So I guess you could say I'm not too impressed. I'm all for clean drivetrains, and I'd really like for waxing to work, but it doesn't - unless you enjoy reapplying it constantly.
