Lots of talk of slapping on the glazes and the like every two months, which is good, but I would really advise the use of a detox shampoo not a normal shampoo prior to that bit of work. Although waxes do wear down over time, there will still be patches of it on the car when you reapply new polish and wax, for a really well prepared even start to the two monthly wax process I detox the car so all wax is stripped and you are starting with a clean surface, normal waxes wont do that.
