I know bud.
Before you wax, after claying you should polish and put sealant on. Claying pulls deposits out of the paintwork and the 'gaps' need protecting ie sealing up again.
The only thing to add after wax is a glaze, which would last for just a few hours in reality! But looks when it goes on.
Wash - clay - polish - sealant - wax - glaze.
Sorry to bump an old thread, but I was about to order Megs glaze as recommended here, and I noticed that in one of the websites it suggested that this product should be applied before waxing, not after it. As I have several layers of P21S already on, I wonder if this glaze product will be of any benefit at all if I apply it now.
Depends on the product and what it actually does. Glaze is a bit of a generic term. If it is something that hardens for wax to go on top off, then it can go under it. If not, it goes on top. Ask the supplier, but I was on the understanding Megs glaze went on last.
