That's more a function of the paint viscosity.  Using an HVLP spray gun,
  you don't normally thin the paint much if at all, so, like with the 
brush,
  you can put on a thicker coat than a normal spray can or gun.

The drawback to using HVLP, like any spray gun is you have to clean the 
thing<:-))
That and they do use a lot of "dry" air.

There are times when a thinned first coat will penetrate into the cracks 
better.

I much prefer the HVLP approach as it uses much less paint, less over 
spray,
and can be put on much thicker than a regular spray. For me, learning to 
use the
HVLP was much easier than doing a good job with a regular spray. You do 
have to
get used to the top heavy, gravity feed and learn the proper viscosity. 
Typically I don't thin Rustoleun at all.
