My combo now that nothing has been able to beat is a Z2 Pro base of 3 coats. Then alternating coats of Opti-Seal and Z8. I have never seen such shine and depth.
Frankly I'm waiting for Sal to put something new or updated out. I talked to him over a year ago when they were working on Z2 and Z5Pro with the ZFX already built in so no more mixing.
