I have had the Quart Finest coating for 15 months now... only soap and water to the SHO... never waxed or anything else.
Pics are below... March '14 pics are above and the original write up is here somewhere or you can see some of the original new application In my ROTM submission.
The link to Wills Amstutz's (Windows and Wheels, Gilbert, AZ) original write-up is at:
www.autopia.org/forum/topic/132346-phoenix-detail-2013-sho-taurus-partial-repaint-water-spots-cquartz-finest/I love not waxing and still no scratches or spiders. The car is a DD, I live on an unpaved road, it sits in the parking lot 40+hours a week in the Phoenix sun with ambient temps well over 100.
Compare to my signature pic which is from the original application. It was a gloomy day... wish it had been brighter as the Quart Finest really makes the metal flake in the tux black pop!
...And underhood before I installed the MDesign CAU today
Thanks for looking! You can't go wrong with CQuart...especially in hot environments where the best carnuba melts off... and it's SPF 80 for your paint. It is about 10 times as thick as the paint and rates on the Mohs hardness scale.
Next update in 6 months.
