Not really, skill is still involved. The advantage lies in less paint
wastage - if you have a good arm.

The downside is that you have to get a powerful one to spray paint thicker
than lacquer. HVLP sprayers that can spray higher viscosity paints cost at
least $600.00. In addition to a larger fan and motor, these units have much
higher quality spray guns than do low priced models. Perhaps you should
enquire about a rental unit.

A friends boat was painted with Awlgrip by a "name" yard on Cape Cod and it
looked perfect. Later we found out that they had used rollers. Remembering
that the quality of the finish (and cost) is directly related to the amount
of surface preparation, perhaps you should expend your effort on that. I did
see one man a the Port Annapolis yard prepping his ~60' motor sailor and
rollering both primer and one finish coat. The final coats were to be put on
by the yard by a professional sprayer. I doubt that the yard gave its normal
warranty.
Last point, after surface preparation, it is the skill of the worker
spraying the paint that makes the difference. Remember too, that most yards
move your vessel into a dedicated paint shed with exhaust fans etc. Two-part
poly paints require protective gear when sprayed indoors. I'd wear a special
mask if I was using a roller outdoors.
