Matt, if you haven't already done so, you might try Mod Podge (Matte Finish). I use it full strength to glue down wood ties directly on the foam and diluted (with windshield washer fluid) on the ballast. I pre-wet the W/S ballast with 70% alcohol then drizzle on the diluted M/P. It dries to a clear, matte finish, plus its tough and somewhat flexible. I also use the gloss finish for water. Handy stuff...
