HO-SCALE SIDEWALKS-IN-A-SNAP. If you've ever labored building realistic sidewalks, this one is a "no-brainer"! These require no modeling skills! Fast & easy! Piece it and go! Complete with laser-etched curb & predistressed cracks that will look like you're back in Brooklyn! Bar Mills recommends weathering the sidewalks with "Color-Place" brand "Equipment Gray" paint available only at Wal-Mart stores. Polly-Scale "Concrete" and "Aged Concrete" also work great!
