Who needs a workout program?

 When you have a boat to sand, fair, sand, paint, sand, fair, sand, paint, . . .

 Second coat - with a touch of graphite powder added to tint the paint gray.  I took the boat outside so that I could see the imperfections.  I also took the opportunity to clean out the garage under the boat.

 Second coat after sanding and fairing - I finally filled in just about all of the pin-holes and glass weave

Third coat - after sanding the bottom again of course.
