When to use what ? IS it just that one looks cleaner and brighter than the other ?
I know what the basic differences are , but when do you use the Polish and when do you use the GPS ? Or do you use polish followed by GPS or is that a waste of time ?
What exactly does the glaze do in the GPS ?
Thank you
