For a decade or so, I've been using "ProLube" on the whole fleet, because it leaves the chain relatively clean and works well at low (commuting) temperatures.
Reluctantly, I find that it does not adequately protect the chains from rust in my garage. But, the bikes that need this protection generally don't get ridden in winter, so stiffness at low temp (a la wax) is not a big deal. What are vintagistas having good success with for the real riders, not the wall queens, but ones that are ridden mostly when it's well above freezing? Ease of use and relatively clean chain are important. If I wanted calf chain tatoos, I'd get a real one. :-)
