I decided to do away with the short pieces of cast roadways I used and make full board length pieces from Kel Seal Brush and Trowable Caulking. Starting with a blank pine board to be the model work space, I laid down to pieces of 2 inch masking tape with a slight overlap on to the board. 3 Thin coats of the KS brushed and dried, I pulled up slowly on the tape, turned the entire road section over. The 3 thin coats had dried and curled the cross section slightly up, so that with the road section turned upside down, the edges cupped downwards nicely. One more thin coat of the KS brushed (using 3" cheap disposable brush), let dry. I then slowly tore off any tape still showing to give the road a rough and then with one brown wash coat of acrylic paint to finish the surface off. Care should be used not to get the KS off the edge of the tape, or it tends to stick to the work surface and be a bit difficult to peel up. Total time spent actually applying KS to the tape for the road was about 10 min tops, with an hour between each coat while I worked on other figures and such.
