The correct term is 'spray-over'. If the present finish is still viable, 
spot filling and a good sanding
will accept sealer and topcoat with good results.

Do you have a low humidity environment?  Try spraying on a rainy day...

Not mist coats, lighter coats than what one usually applies with lacquer 
but still wet.  Spray 6' to 8" from the surface.  Once you get the spraying 
technique down, the process becomes almost effortless. So much so that 
you'll probably want to drop your rates since it's so easy :-)

I have a tendency to spray heavy. It is a bit of a chore to keep reminding 
myself to lighten up.  I don't spray all that often so I get rusty and 
forgetful.
You saw the finished pieces here in my shop, some rubbed out some were not, 
and the ones which were not rubbed out looked better than most
of the refinishers out there.  The times I do remember having orange peel 
was in the dead of winter when the humidity was way down and'or the area
was too cold.  I time refinishing projects now for warmer weather, when we 
can do the sanding outside and not have to vent heated air to the outside.

Get the spraying technique right and a handle on the heat & humidity and 
you'll be on track.
