Yes polish, seal and then wax.
Good shout on the OCW.
Spray waxes/sealants such as Optimum Car Wax (OCW), Prima Hydro, or Duragloss Aquawax are all worth purchasing for times when you just want to washand dry as all can be used on the paint while it is wet from washing and removed while drying leaving a just detailed look.
I use one of the above each time I was my silver Pug and all work well. I give the nod to the OCW if you want to grab something like that to maintain the look between monthly waxing.
