It doesnt settle dust like you would think on a normal wax coat. Normally I don't wash my car for 2-3 days and a light dust layer comes on it which gets blown away when I drive. Otherwise a good quality wool duster is all you need to get rid of the dust.
It does require maintenance but not anything complicated. I wash my car with CeramicPro Sport and CeramicPro shampoo that I bought from UK on a weekly basis. It's been 7 months since I bought it and it still shines like new - even in Karachi. And my car is parked at seavew Dolmen Mall open parking on a daily basis.
Personally I have a huge collection of products from Autoglym, Chemical Guys, CarPro, Nanoskin, Dodo Juice etc but aster coating it all I use is a Karcher K2, Handheld Blower, a good prewash and pH neutral shampoo, and then use a good detailer. Works perfectly for weeks on top of the coat.
