I started with sandpaper not really happy with it. I got .030 styrene and roughed it in tonight so far I love it. Before I go to far I need ideas on good ways to secure it to foam,painting it to look like western/desert concrete and other detail ideas. The thing that I lucked out on is that I bought it in small to medium square pieces so it has that real life cut between sections like you see on real concrete roadways. Thanks.
