So no one Zainos?
I always within the first week or two (depending on time and weather) claybar and do a full Zaino treatment. Then I only go in and claybar and re-apply one treatment of Zaino (Z5 and Z2) once a year.
My cars have come out better than ever doing it this way. My Trans Am hasn't had Zaino put on it in almost 2 years and it still beads with "bigger" water droplets than most do with waxing...so its still on there. Though this year I think I'll get both the TA and the WRX Zainoed well so they are on the same schedule.
Zaino is a pain the first time you do it, but so easy afterwards.
Love the Zaino!
