i did the whole zaino process with one layer of z-2 a few days ago. i'm planning to add another layer today. my question is do i need to just wash the car with z-7? or do i need to go through the whole process again

 

If by "whole process" you mean wash with Dawn and clay bar, you will be stripping off the previous Z-2. Just wash with Z-7 and add another layer. You can also use the ZFX accelerator and get multiple coats on in one day. Also, Z-6 between coats is great.

Hope that helps.

 

thanks, that answers my question exactly, i was just wondering if i needed to use dawn/clay bar again or just the z-7
thanks again

 

Wash it with Z7, hit it with some Z6, then add a new coat of Z-2. Every tenth coat use the Z1 one again.
