Waxing good? Absolutely!
Last year I gave it a try so now Been there and Done that. Was it worth it? For me no. I ride Ravel roads. That is torn up asphalt, small gravel, chaliche, sticky dirt, and some times damp. For me to ride when its wet is now foolish.
What I found is that I did not pick up the dirt as quickly but I did pick it up. Considering the time I spent waxing my chain I found it not practical. If I was doing competition I would wax. If I was doing true road biking I would do it. Of Touring and Mountain biking I have unfortunately no experience.
If you have never done waxing of your chains then certainly give it a try.
For me when my chain starts looking a little dark I just liberally squirt ATF on my chain then wipe it off to get the dirt off. If I pick up heavy mud I take the hose to it then do the ATF. And yes I do have a box of unused, fancy, specialized, lubes that over the years I have wasted my money on. Ha.
Note: It would appear that modern day chains are not lasting as long as they used to. But thats another thread...
