Steve, when the fur is ready for the extremely highlights in some spots of the figure you can try with a light amount of a mix 4-5 part of white ( titanium white oil ) and one part of chrome silver Testor enamel . Pay attention the colour has to stay only on the surface of the fur and try to avoid the lower parts where there are the shadows, so it is better for you to use a small brush ( 0 ) and paint each hair fur , that obviously depends also how detailed the sculpt is ..hope it could help..
