Hello all! I'm getting to the point where I have to start contemplating the construction of roads on the layout. As I'm looking into the various methods and materials, I find the use of "Smooth It" and "Top Coat Black" to be a bit daunting and am looking for a simpler approach. I recently saw a video (somewhere) where the modeler suggested the use of sandpaper to model asphalt roads. He was using 120 grit sandpaper for this, which I happen to have some of. But this grit is much too large for N Scale. So, my questions are these; 1) Have you ever tried sandpaper to model asphalt, and what did you like/dislike about using it? 2)What grit do you recommend using for N Scale? Its not that I'm incapable of trying several different grits to discover for this myself, I'm simply looking for ideas based on other people's successes. 3) If you've used, or are using, sandpaper... how are you addressing joints in the sandpaper where two pieces have to butt together? Thanks for all of your input!
