Wow! Been almost 2 full months since I did any work.
Last post I cleaned up track using 1500 grit. It has stayed clean!
I am filling in spaces between yard track right now - use less ground materials - you know, the good stuff
Hope to break out the airbrush soon.

Unless you're planning on the areas between the tracks to look like concrete, you might want to try a bed of fine sand, wetted down and glued with diluted white glue. The surface of the sand (unevenness) might more closely resemble the prototype ground as a base for your vegetation and finishing touches.
Research; it's not just for geeks.
Can you post a picture?
