i have been using eale one wet look wash and polish.
a lot of people here use meguires...i dont know why eguires is better. i dont know if there is some secret dangerous thing in the eagle one, but i like the look of the finish.
gets washed about every two weeks, and polished every 2 - 3 months, depending.
You wash your car like it was your firstborn child, you tend to its needs like it was your own body, you protect it like it's your family, then you drive it like you stole it.
