Coating black mustang with 2 coats cquk 3.0 followed by Gyeon cancoat in March. Buying all stuff now as I want to be ready. I have a gallon of Shinesupply clutch I will be topping with but also want to add to ech20 as drying aid and QD. Every two months lwould like to top with something more substantial. Just spent poop load on polisher, pads, above mention supply’s and lots else and only would like to buy one of the three mentioned in title. Any suggestions? Thanks in advanced
