I went to the dollar store and bought one of the sponge mops then I wrap the sponge in a terry towel and stand on a ladder to the side and put the wax on and change the towel and buff it off. Just make sure you get the cheapest made in china all plastic mop you can. You want it to be very light and you dont want any metal on it. You can cut off the fold over water wringer to lighten it even more. If you use something like Starbright fibreglass wax/polish it buffs off easily.
And make sure it has a relatively soft sponge when dry not one of those that have a rock on the end till it gets wet. But most of the cheap ones do have a soft cheap foam head.
