Quoted from Darcy:
Think of the wax as a sacrificial layer, between the ball and your playfield. 2 or 3 thin layers applied and removed between applications, will be better than 1 thick coat. The thicker the coat, the harder it will be to remove.
Well it doesn't exactly work that way.
Whether you apply the wax very thinly or really lay it on heavy, the layer left behind after you buff it off will be the same (assuming that you got full coverage).
There is great debate as to how much benefit there is to doing multiple coats. I would say that there is a general consensus on the auto detailing forums that it makes little sense to apply multiple layers of a pure carnauba wax.
Synthetics, on the other hand, can be layered to create a slightly thicker coat. The important thing is to allow each coat to cure thoroughly before applying the next coat, or it will not bond/layer properly. While some people will put up to 8 layers of a sealant on their car, this is of very questionable value. Many agree that 3 layers of a synthetic is probably the most that you can apply and still get some slight "layering".
But either way, applying the sealant thick and heavy will not leave behind a thicker coat than applying it thinly. In fact, the opposite can be true, because applying a sealant too thick can prevent it from bonding properly.
EDIT: I'm an idiot. I read your post completely wrong. What you said is accurate.
