This is what I did to prep prior to Zaino.
Washed car with Dawn (strip wax/oils)
Clay
Wash Z7
Polish: 3M PIII-MG followed by Menzerna/FP (Swirls were not that bad-however, picture looks better on Web than close up TBH with you, needs more FP polishing)
Wash: Dawn (remove oils from polish)
Dry
Wash Z7 (remove any Dawn film)
Z6 prep
ZFX/Z5: 3 coats one day (garage, no driving) Z6 between coats
ZFX/Z5: 3 coats again following day Z6 between coats(garaged)
ZFX/Z2: 3 coats Z6 between each. DONE!!!
Maintained with Z6 prior to and after driving car.
Any slight feel of dirt, off to wash with Z7 and dry with CWB and Waffel Weave MF. Follow that with Z6, wipedown with CBT or DFTowel.

Deanski
