You might want to consider drawing your schematic on paper, or cover paper and mounting behind 3mm Plexiglass or Lexan.
Relatively easy to reconfigure if changes are made.
I have done several panels with a drawing program. Printed one copy normally, and a second copy backwards, then attached them back to back, so when working in the back of the panel you can see clearly where parts are located.
Also easier to keep clean.
