Everything not to be painted white is carefully masked. Very carefully - the last thing I want is white overspray on that beautiful new green hull (is it too light???) The boat is blown off, all dust swept outside, the doors pulled down, and walls and floors wet down with the firehose. A mate is running a tack rag over the surfaces to be painted, to remove any final dust, and static from the surface.
Pallets have been stacked around the hull, so that I can start spraying at one end (back corner), and not have to stop until I get back to the same spot. Therefore no dry edges. Someone follows pulling the airline through the water, and another person is ready with a pre-mixed container of the 2-pak paint mix, continually stirring, and filling the spray-gun pot as I spray. Stopping for a couple of minutes is disaster, so the final spray stage needs to be planned pretty well....
