Have to chime in here. You can have a perfect looking car. You need the right materials, tools, patience and time. Sapphire is a very nice color.
First of all, I do not understand the above comments that simply running a micro-fiber towel over your car is going to produce "swirl" marks. Swirl marks are actual defects in the clear coat either from the factory, environmental conditions or poor maintenance. Dust is not going to produce swirl marks, unless you use a dirty rag and grind the heck out of your car.
First of all, the basics. You need to go over your car with a fine tooth comb and clean the paint, polish and wax. I use Meguires. Others have other opinions. Meguires is a three step process. It takes time. Period.
Next, once you have it waxed (by hand or machine) put the car under a car cover. You will not have to do all that much maintenance on exterior. Keep the dust off of it in the first place.
I use the California Duster and have had no problems with it leaving swirl marks after a proper waxing. Good luck.
