i just had an idea tonight for making another look to my future scale buildings and it works so well I just had to share!
Using nothing but a light diffuser from a fluorescent light fixture I trimmed the ribs to make a brick pattern, layed on top the Coroplast and sprayed.
Here's what the very first test pieces look like. So easy and can use same template over and over.
. This kinda puts me back in a building mood.
