When it comes to model railroading, I'll never be as good as some of the masters we have here .. but I like to save a buck also .. I learned that from Lee .. sometime back I picked up some paper model grade crossings .. I have a few Atlas rerailers, and other grade crossing built .. since the M&O is always in the sort of present .. I figured it was time to see what I could do to hide these rerailers .. here is my attempt ..
1) print the crossing on cardstock.

3) I use some cheap craft paint varnish on the paper - front ant back .. also acts as some glue ..
4) place the paper on the track, align the "concrete sections"
5) I use some diluted concrete paint to give the paper model a little better "concrety look"
