The glaze however is after the polish stage.
Imagine you wash your hands in thinners.... they're real clean with no dirt but the thinners has dried them out.
This is what happens when you polish your paint. What would you put on your hands if you washed them in thinners? Moisturiser?
This is exactly what a glaze does, it acts like hand cream for your paint. It replenishes lost oils and deepens the shine after you have polished that becomes even more noticeable once the finishing wax is taken off
Hope that helps
