excuse me zainoholics, since i live up in the northwest we get pissed on most of the year it seems and since i'm lazy and don't care to wash or wax car often i found that out of all the things i've used thus far, the best that kept car clean the longest is DURA-SHINE.
It works well, only downside you won't get a baby bottom smooth feel after the car is dry.
I noticed the water spots, dirt, and crap didn't stay on as much.
try out sometime.
