I posted a photo of a coal tower and a photo of the model of a coal tower I had made and asked for advice on weathering it .  I have tried everything that has been suggested.  Thanks to everyone who pitched it.

Rather than trying the options on the tower itself, I have tried options on sytrene which I have temporarily attached to one surface of the tower.  See photos that follow,

hello,
i need to glue wooden coffee stirers to a piece of bare plywood, what would work best, wood glue or lock tite gel controll superglue?

im looking for ideas in making the roadbed more realistic on a section of track coming down a hill that sees a lot of coal traffic( setting is coal country) during the early 70s.at this point the roadbed/ballast is coal and cinders. my guess the diesels would be applying sand to the rails, what color would the residue be?

Somewhere I read an article about using "Green Fiber" insulation with drywall quickset plaster as a substitute for sculptamold and of course when I'm about to need it I can't find the article.  Does this ring a bell with anyone? I'm mostly wondering the mixing proportions which I guess I could determine by trial and error, probably mostly error.  THANKS!!
