I've always hand painted Unitrack track rails with an acrylic based
paint and a 18/0 red sable brush. (You can also use an oil based paint.)
On the "new" JJJ&E, the rails are going to be a grimy black, so this time I tried Neolube # 2 which turns metal black. It is a conductive agent and prior to this I used Neolube # 2 to blacken steam locomotive drivers and valve gears as well as the side rods. The Neolube does a great job in blackening the rails and I'm using it as well as grimy black to weather the rails of the "new" JJJ&E. The Neolube can easily be wiped off the top of the rails with a small rag. Since it is a conductive material, there won't be any electrical concerns during application. You can use a 18/0 sable brush to apply the Neolube.
You can order Neolube # 2 at MicroMark and it can only be shipped by a ground service, since it does contain alcohol.
