Track Tack It is the easiest and cleanest way to ballast your HO, N, O, or S scale model railroad tracks. Simply mix 2 parts ballast with 1 part Track Tack It, ballast your rails, and soak/mist the laid ballast with water! It will become tacky right away and will be "rock hard" the next day!
No more need for messy concoctions of white glue, water, soap, and alcohol to get your glue to spread, or having to remove glue from the rails. This is a 4.5 box for large projects.
