Apparently both the Meguiar’s NXT and the Meguiar’s Gold Class wax have a slight cleaner component as well as a wax. I was considering using the Gold Class as what is called a ‘topper’, to try to get additional depth in the wax coating. The Meguiar advice appears to be to put 2 coats of NXT on and leave it at that.
My Cadillac CTS looks great with two coats of NXT on it now. I guess the next step would be to start with a clay bar treatment, then put the NXT wax with two layers, or clay bar then cleaner wax then the NXT x2.
