I have a HO scale Kato C-44-9w loco in C&NW green and traditional yellow (engine # 8717, and need to paint all the grab irons and handrail parts, which come separate on sprues, and I believe are made of delryn or some other flexible plastic. Has any done done of these, and if so, what paint type and colors did you use? I don’t have ready access to a hobby shop to visit, so would have to order online.
