Just purchased another round of Cquartz, CSL and ExoV4 coatings for some projects at home from AG. This question is either blasphemous or overkill but I just thought I would throw it out there as I am still fairly new to this. So from some durability tests that I have seen, Gliss seemed to not hold up as well as I would have thought. Exo however seems to be really solid. The reverse appears to be true for the base coating with Cquartz being very durable but CSL checking out a bit early.

I know that Gtechniq doesn't recommend mixing there stuff with other brands not knowing what the compatibility would be but the adventurous side of me would like to try Cquartz for a base and some Exo for a topper. Any comments or anyone tried this? Thank you!
