What cleaning polishing methods/products are you going to use/are using?
Without proper preparation, you will not reap the true benefit and look out of the wax.
On my silver car today, I clayed, Klasse AIO and a coat of Autoglym EGP. I will add another coat of EGP next week as a starting point for the winter months, then maintain with Optimum Car Wax after washes.
I have found that AIO and EGP or Klasse SG give very sharp clear reflections. Looks ace under petrol station sodium lighting!
Also on silver, back in the summer, I used Clearkote's Red Machine Glaze and 4* UPP, which gave me a 'pop' finish and a look that I have yet to equal.
My first combo on silver was Vanilla Moose and EX-P, which was nice too.
A few weeks ago, I was very impressed with Clearkote's Yellow Wax and Optimum Car Wax as an LSP, which is the easiest wax product I have used and looked great and stayed very slick up until today when it was all removed by AIO.
