I have a new Nemo blue which is already showing fine scratches after 4 weeks and 3 washes.

I am trying to rank (Pareto chart) the sources of fine scratches. How would you rank them?

I have mixed feelings about using a duster to remove dust from an otherwise clean car.

2) drying a car that has not been thoroughly & gently washed.

Short of hand washing the car yourself every time, I don't think you will ever get rid of the fine scratch syndrome. But I think this is easily fixable with a good polishing compound.

Are you hand washing your car? If so, what are you using to wash it? What are you using to dry it? (If you're taking it to a car wash, even a hand wash-type place, look no further, that's where it's happening). You also say you have "mixed feelings about using a duster"....does this mean you've been using a California Duster on it? And, are you quite sure those scratches weren't there when you took delivery a month ago? Don't dismiss that possibility unless you're sure; my wife's brilliant black wagon looked fine to me when I picked it up on delivery day, but upon very close inspection at home, I realized that there were a multitude of very fine swirl marks all over it, as delivered, obviously caused by using improper improper tools (mostly likely synthethic fiber drying cloth) when it was prepped for delivery. So now when I finish detailing her car I can honestly say that it looks <i>better</i> than the day we got it.

from the dealers wax job. Washed it twice with Dawn, gave it a coat of Zaino Z5 and the swirls were gone. Did a Gloss Enhancer and then a coat of Z2--I've never seen such shine with so little work (compared to other systems.)
