Deck painting while at dock??????

[Oldwheels]

Tell me your experience, opinion,savoy advice and criticisms.

I am wanting to paint my deck while at the dock. Been reading all the paint manufacturers technical data sheets. Prefer a 2 part polyurethane but may be forced to rethink this.

May be able to spray but seriously roller and brush may be easier.

The questions I have are exposure to elements during drying. Sun, dew, etc.
How do you second coat when you have to walk on first coat?
