So I am still torn. Right now, I have BF Crystal Coat and 22PLE Signature on my two rides. I found the shine very good but not as good as Zaino and that is what I am after. I don't mind washing the car and "topping or layering" any product so I am seriously considering going back to Zaino next year. I was looking at Car Pro CQuartz with reload/reset as that regime may work. I don't see anything like that with Optimum, but Gloss Coat looks incredible and I would love to try it. Also, I found this discussion very worthwhile and interesting since coatings are the future and I would rather use the best and most current technology as long as you get the best shine / reflectivity possible.
