Greetings; I am back from my adventure to South Africa (3'6" railroad if you are interested) and I'm back at work on my layout. I'm using Woodland Scenics risers, etc. I have scribed out all of the mainline areas and have actually pinned the risers to my blue board. My question is this: does anyone know of a liquid adhesive that I might spray on to set the risers in place? My original plan was to place everything and then go back and glue it all in place once I was satisfied with location, proper curve radius, etc. Now I'm looking for an easier way to do it!!
