I'm getting ready to spray the hull of a boat that I recently primed
with a roller/brush. The boat is a 21' rowing shell that has a beam of
about 22". I'm using an HVLP setup. Should I be spraying this by
starting at one end and then spray one lap the complete length of the
boat and then make successive overlapping passes for the complete
length of the boat and so on? Or, should I completely cover the area
where I am standing and then work my way down the boat? I can
definitely see pluses and minuses for both approaches. FWIW, I've
sprayed a fair amount of furniture, etc. but I've never sprayed
anything that I have "walk" with the gun to complete the job.

Also, this boat is hard chined. Is there any special technique for
dealing with the chines?

Thanks for reading,

Paul,
If you go find an aircaft painter, he will tell you that "walking the
gun" is not an issue.
You have two choices:
- Paint a patch and move
- Walk a layer and then walk a layer back (that is what I like to do)

The former can leave edges to rub out on a hot day. Keeping the whole
surface wet is not easy on the latter.

If you rack the shell up, you should be able to squirt the entire boat
in a single shot.

Good Luck Guy
