I am working on my HO set and have gotten to a mountain area where the mountains are very steep so there would be little vegetation mostly rock face, but I am having a problem getting the rock fact to come out right. I have been trying just brush painting but the colors either are too bright or too dull. What I am looking for is some ideas maybe either for weathering or doing the rock face right. Thanks, Joe p.s. If this should go somewhere else I am sorry but i'm new and figured since it is for a HO set the HO forum would be appropriate.
