Personally, I found the wax gunked up in a week and became unforgivably slow / sticky. But it was pretty good for a couple of days. I quickly reverted back to GT85 dry lube, piss thin and have to re-apply every few days but it hasn't gunked up once.
Where? Did you wipe the excess off when it came out of the crockpot? There doesn't appear to be enough wax on my chain to build up anywhere but I guess time will tell.
Morning! :)
First ride on the home-waxed chain. Sooooo quiet! Love it.
