The first wax i used was Megs No16. Its a brilliant entry level wax,and last for ages,and its cheap too,especially taking into account how big the pot is. Id use it with some foam applicator pads,rather than a MF cloth. It will train you to put on and buff off properly,as being white,you will see the next day where you have missed.
I think SRP is a great product,and should be used after a clay,then wax on top.
