...while I'm waiting on connectors to arrive for my signals project ...back to creating more foil-based rock lining for my tunnels!
Drying on the back deck before another light spray coat to mute the strength of the white accents on the rock face. I just need to remember to pull it all in before the typical afternoon summer thunderstorms. 
What I love about this technique is that it's so easy to work with. Foil can be cut with scissors to required size, and can be easily adjusted/molded for small mods or clearance issues.
