Sounds like you're fine, then //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
Although, honestly, I would recommend against dusting the car every morning. Even with a microfiber cloth. Dry microfiber does cause the tiniest of swirls, and after several years they can build up into something that's visibile. The less contact you have with the paint, the better - another reason why sealants are FTW!
If you must dust, at least use some external quick detailer on your cloth to reduce friction. Although if you're willing to wax your car every month, it sounds like you wouldn't mind polishing lightly polishing it every other year, either!
