1/4th (of the 200ml pot) should be enough to do 10-15 (and even more) applications
This is a hard wax made from the highest quality carnauba, when you swipe applicator on it, very minimum wax gets on the applicator (due to the hard nature of wax) but when you spread it on the car surface, it spreads very very far. You have to apply thin thin thin (which is a rule with all waxes but more so with these high end waxes), which means it should be visible applied at a certain angle only. Keep going further and further without need to apply more. Its durability is around 3 months (keep 2 in mind) if you're washing with a car wash (and not surf/detergent) and have applied this wax on a clean base (using any good pre-wax cleanser/polish, that I can look in my inventory and rebottle some if you dont have it).
Price for 1/4th would be 3000 (+shipping ~150) and will be package in a quality brand new pot.
