Update:
So far on the roof all four coatings are holding up well. The first pic is during a light rain. Duragloss is the driver's front, OC 2.0 is the driver's rear, CQUK passenger's front, and Detailer's Pro is passenger's rear. If you look in the second pic (it's very hard to get a picture of this) you'll notice the OC 2.0 and CQUK are virtually dust free compared to Duragloss and Detailer's Pro. This has happened consistently.
Hosing the coatings show slightly stronger performance from CQUK and OC 2.0.
Now for the second interesting part. The roof prep was intense and there have been no bonding issues. The rest of the car was prepped with just Duragloss squeaky clean and in some areas the coating failed. A quick clean of these areas with IPA and Eraser before another Duragloss application has fixed these issues. So in my experience the prep polish alone was not enough. FWIW, my wife's car is a factory single stage Milano red. I'm not sure if the paint is porous or what, but I had OC 2.0 fail in the past on it. With superior prep no issues.
Ease of applicaiton
1) Duragloss
2) Detailer's Pro (flashes fast)
3) CQUK (I'd almost make this a two since you can simply buff the whole panel after 1-5 minutes and do the second coat within 1 hr as opposed to 24 hours)
4) OC 2.0 (I don't care for having to look intently for high spots and having to be careful not to overbuff-plus it's very tacky during cure) Note:4th place does not mean it was difficult
So which did I choose for my new 2014 Silverado and my mother's new Buick Verano?
CQUK!
Reasoning:
1) Less dust buildup
2) Easy application and ability to buff the entire panel made less worry about high spots
3) 1 hour recoat, ability to layer
4) Specific manufacturer-made booster products like Reload and prep products
5) Better performance than the nano sealants
6) Looks better than opti-coat
7) Great support from Corey
I'm going to continue this test on my wife's car and update it as things go on. FWIW I used the leftover OC 2.0 on my wheels and the leftover Detailer's coating on things like headlights and taillights.
I've since used Dlux on my trim and plastic and have fallen in love.
