Wash it really really good. Clay bar, and then Zaino 1 which you leave on, then put one of the Zaino polishes right over the dry Zaino 1. Lot of work and use only micro fiber towels. finish with a Zaino Detailer or Maguires detailing spray. This is way too much work to do all the time but is what I do when I want to win an indoor show under the flourecent lights.
