I would slightly disagree. Go with ZFX instead of Z1. You'll save yourself a lot of time waiting.
T-Red forumula: ZFX, Z5, Z6, Z7, Z18
BTW, Zaino does not have a swirl remover. It has a very mild swirl cover, Z5
If you wnat to save soem time and money and can accept waxing every other month instead of twice a year, pick up S100 SEC and wax. $24 at your local Harley store, 30 minutes of work, better depth.
