I agree with Jake, the pride and satisfaction of doing the job is the reason I chose to build a boat in the first place. So why would I take the best part and let someone else do it. I work with complicated finishes all the time, sometimes they take practice, but usually they come out great.
Plus its always going to be cheaper if I do the job. A brush and a roller is easy and cheap.
The health issues are real, but they are not so scary that I would outsource the work. Just part of the consideration of spraying vs rolling.
