I know it can be used between every coat, but that seems like overkill. I know you can apply up to 3 layers back to back in a 24 hour period. But how often should you throw some ZFX into the mix? I'm talking time wise. I know Sal recommends no more than 10 coats before adding ZFX to an application.
I know he recommended using Z1 once every 6 months on a daily driver. Is it the same rule for ZFX, assuming you don't go over 10 coats?
