Where I park is underground but after a day its covered with carbon dust. The car is washed weekly and I hit it with the detail spray every other day to get the dust off. Needless to say, the car is staying almost spotless all the time. I don't see any swirls in the paint and the shine is nice, but after seeing the shine that some of you have on your cars I'm thinking you had better light for a picture or I need to polish again to bring out more dazzle in the paint.
Thanks for the advice. I'll wait the 6 months and try again. Maybe its time to practice some more on the Intrepid.
