My 17 H Spyder is 100% wrapped with XPel Ultimate. I went with CQuartz Finest on top of XPel and must say I am not happy with CQF as it holds dust in comparison to my 16 Cayenne Turbo S which has no clear bra but coated with Ceramic Pro. The Cayenne can literally go weeks without showing dust whereas after one drive, the H seems to attract dust.

Also, I can take the Cayenne to a handheld car wash, spray off the car and zip on down the road to air dry and have no spots. Can't do that with the H, it leaves spots.

All that being said, I have to wonder if CQF is just inferior to Ceramic Pro. If applying CQF atop XPel has affected its performance. Without the Cayenne being wrapped with XPel and Ceramic Pro applied atop of the wrap, I'm not sure I am giving a good comparison. Looking back I should have just coated the H with CP as well. To do that now would mean the wrap would need to come off and start all over again. That's just too much $$ to throw out the window.
