Hi everyone. I have ben out of the hobby for about 25 years and just getting back to this wonderful hobby. I did not realize how much I missed it. Any how, I'm thinking about using cork roadbed, but the other day, at the home improvment store, I saw some stuff called sill gasket material. Has anybody tried using it in place of cork? It's like a plastic, and colored blue. I was wondering if you can paint it, and will white glue and ballast hold to it. Thanks for any info you all might have.
