so I have a few applications under my belt now. I've gone through a full 50ml of cquartz UK and did a H2 with cquartz and dlux. I found the UK edition a little more gummy during application. I did not have any issues, but I was surprised how easy cquartz classic went on vs. UK. I kept adding more product to the applicator thinking I was not using enough. Results were pretty much the same. All vehicles I did were decontaminated with iron x, poly shave blocked, and polished with essence on a mequires microfiber pad using my flex. You guys find that classic applies easier?
