Personally, Not sure that the labor is the MOST expensive part, then again, depending upon the prop work done. I painted my 30'r by myself in under and hour per coat, with another hour at best hitting the lead, aft parts of the keel, rudder and bow section of the boat where the ablative I had wore off. Then again, with yard rates approaching $80-90 and hour, that gallon of paint at $160 is pretty cheap, with some as low as $100 to the mid 200 range.......I used 80% of the gallon for a double coat......
I too am looking at a hull strip, about $1000-1500 to take it down to gelcoat. in this case, the labor is the main item.
