Hi David, I have used Swisswax on my Mog, and jolly fine stuff it is too. Recently I have switched to using Dodo Juice, not because I was dissatisfied with the Swisswax stuff, but I do like to buy British whenever I can.
I'm not the world's most assiduous cleaner of cars, I tend to re-wax mine about every 4 months or so. All I do is wash it off, go over it with paint cleaner, and then a couple of coats of wax. Takes me a couple of hours or so.
