The final of my haul from the Wreck Age booth at Adepticon are these roads. They were part of the Wreck Age Kickstarter and are still occasionally available.
They’ve got a really neat texture and are made out of a semi-flexible resin. It takes to being drybrushed quite nicely, and I splashed on some other color to give a bit more interest.
The one with lane markings was done sponging yellow paint over the masked road. I should have measured the masking, since the spacing seems pretty off.
