Having just used the ECH2O at 1:10 with an additional 1 part of Gyeon Cure, I can say that combo is a real winner when it comes to topping the car off. I have Gyeon Mohs on my car, and it is ever so slightly "grabby." There is a whole new level of slickness after ECH2O/Cure is applied.
I am curious to see how this shapes up when it rains.
As far as the topic goes, I had a terrible time with CarPro Reload straight up as well as 1:1. I had my bottle in 2014/2015 before I tossed it. I've heard from some that the reformulation is better, but for me, it's like putting a dollar in a vending machine and seeing my bag of potato chips get hung up on the screw. Not going to feed that baby another dollar!
