If urethane is requested, the manufacturer will most likely not use gelcoat in the mold and apply the urethane finish after assembling the parts. I know my Genesis was done this way. Ready to spray urethane is about 10# per gallon and it would take about 2 gallons.

Not true of current production yet John. Ships are molded with gelcoat, then filled and sanded, followed by finish paint. This avoids the million pinhole problem,
Maybe at some point they will spray primer in the mold, followed by lamination. That would require knowing and tracking which parts go on a painted ship, plus some process and quality controls.
FWIW
