Once you get the base coat on you can alternate between Z2 and Z5 depending on what you want. I usually use Z2, but once in awhile I'll throw on a coat of Z5. Some people use only Z2 and some use only Z5. It just depends on the car and what you like.
Z2 and Z5 are totally compatible and interchangeable, mix and match as you like. I think Z2 is a little shinier and Z5 is a little more of a filler, but they are so close it's not a big deal either way.
