I was able to get a new cast resin roof from the Hobby Gallery and I painted it using craft paint and then weathered it with pan pastels. I repainted the brick on the tower box car red, the wood trim, widows and doors Pullman green and the cement weathered concrete. I painted the interior a dark gray to town it down from the white. For mortar I uses DAP fast and final spackle. I heard about using this on the Mike and Scotty Pod cast. I have a bit of touch up to do, add a some details and build the exterior stair case. New kits are still available from the Hobby Gallery.
