Candy apple paint

I´m going to paint the rear fender on the wifes Chrysler.
It´s a Candy Apple Red color with a silver paint in the first layer.
My question: should the silver paint be completly dry before applying the candy red basecolor? For how long should I wait to apply the basecolor?
I belive I´ve read that the clear should be sprayed within 24 hours.
But how about the red basecolor on the first layer of silver?
Any help are most appreciated
Many thanks in advance.
