Pavement Markings

I am trying to use the "2D Stencil onto 3D Surface" tool.  I have several adjacent surfaces that I am stenciling onto.  It looks like wherever a pavement marking is on two surfaces the pavement marking bombs out and either doesn't show up at all, shows up only on one surface and not both, or shows up but is way too thick.

 

Does anyone have any thoughts or suggestions on this?
