zaino appears to have a loyal (fanatical

) following. i have a silver tour and use meguiar's. seen a silver tour with zaino and didn't/couldn't justify the price difference.
if you don't have the time, (or money) use a good car wash soap and meguiar's cleaner wax and you should be good to go.
i'm sure the zaino following will chime in here shortly. :rolleyes:
