Having a black car I have been drawn inevitably into detailing. I've not heard of this but googled it. There's YouTube reviews and mixed comments on various websites if you're interested.
It probably wouldn't be my first choice, comes into the too good to be true category.
If you want to get into it, there are plenty of sites and YouTube tutorials that will give you fairly consistent advice about the best products.
I'm largely using mainstream stuff (Meguiars mainly) and it works for me.
If you want a great job, sadly elbow grease is unavoidable.
