Less is best
Don't to use too much product. It will become harder to remove the thicker the wax is layered on the paint. It only needs a microscopic layer to work, so don't waste the wax by applying too much - less is best. It's at this point where if I was a bit more of a corporate head, I would be telling you to use as much as you can, as you will be buying more product, more often. A good thing for us; the terrible truth is, for it to work at its best, you don't need to use that much, so it is better value and the one bottle will go a loooong way.
