Painting boards and sanding the hull

I've decided to spray paint the topsides.  Spraying has gone very well with the boards that will cover the settee.  I think that if I tape and cover the boat with plastic, and skirt it with painter paper, the painting itself will go very fast. 

Most of the sanding is done.  I plan to go over the topsides one more time and then fill and prime (which also is a filler) the defects in the topsides, sand those spots again and it will be ready to paint.

Weather calls for no rain for six days.  This seems to be the time to do it.
