I did my first ever detail today with my new DA (I'll do a little write up later) the wax I used dodo juice Diammond White hard wax, I only ordered a sample size pot (30ml) as I wanted to see if I liked the wax first and I reckon I used about 2/3 so is about 20ml of wax roughly the right around to use on a car? I personally reckon I slightly over applied but obviously I have no idea as this was my first time....
