yea, i had the cquartz on my car, i would say it's awesome, it sort of makes the car easier to maintain with the layer of protection, i didnt really believe it at first but yea...
here's a video showing its durability.
i dont have the guts to do what they did in the video, but yea...
i havent tried the DLUX but apparently in the UK it is getting positive reviews, i think would be really good on those faded trims and bumpers.
let me know if you want any advice on it, i will be more than happy to help, i am sure every car lovers here in the forum wanted to keep their cars looking at its best.
