A quick an dirty way:
1. thin layer of wax, spread evenly without buffing.
2. 1 drop of water, circular rubbing using cloth, light to moderate pressure
3. repeat 2 until get shine
At first, you may need to do step 2 many times (5-10 times), but after you are familiar with the process and can feel how much pressure you need when rubbing, then it would take very little of water.
It can't be right to be so excited about finding a new (to me) way to get a mirror shine! I'm going to give this a try later.
