Hi All, I purchased a set of the Woodland Scenics paint pens in order to make my new Kato Unitrack look a bit more prototypical. I tried it on a sample piece and to be honest I'm not entirely happy with it. It seems to me that the paint tip is too large to really get into the side of the rail. Anyone use these and have some tips? If these don't work, I guess I will consider getting a fine tipped brush and doing it that way. Thanks!
