Kinda different and the same. Imo C2 offers more a nano style sheeting and beading and seems to last better.
As I said before even on a dirty car the C2 was still beading and sheeting to a crazy standard. I actually have a video i'lll need to upload for you guys.
Reckon that's because TC is more oily, making it wax-like? That's my reasoning for thinking TC has a glossier finish.
