Prep work? We don't do stinkin' prep work!

Preparation for any project is often the most important part.  Without a proper foundation, the project will fail.  However the prep work is usually covered by the finish work so many people short-cut or skip this step.  The photo shown here is from a freshly painted re-sale house - they even painted the electric panel.  Too bad they did not clean or prep anything as told the painted lizard skeleton at the bottom of the panel.
