I’d say neither. CarPro CQuartz UK 3.0 has many more testimonials and has been proven for years. I took a chance on Blackfire Glasspro Windshield coating and it wasn’t very good. So my recommendation is to go with what is proven.
I have not used but since you asked about these two and not my general recommendation I’ll try and answer best as I can.
The Profi is their newer coating and professional line (Profi means professional in German).
Being newer tech and marketed as professional this would be my choice. I would say it’s a good product based on limited reviews and that I have not seen a bad product in the wolfgang line.
