using wodland scenics rusty rail markers properly?

[derek]

Just wondering if anyone has used W/S rusty rail markers? When I try to paint the side of my tracks I find that the tip "rides over" the plates, so I just get paint in the spaces between the sleepers and have to spread paint with a fine brush, totally defeating the purpose. On the video tutorial on W/S site this problem doesn,t occur. Thinking it,s my track maybe- basic Hornby track. Maybe the gap between the underside of the rail and the plate is too narrow to allow the marker tip through? Thinking of trimming the tip with my trusty Stanley knife?  Also while I,m at it, weathered tie marker doesn,t seem to make any difference to the sleeper colour. They just seem to stay the same black colour. Has anybody  else found this? Patrick told me he used these track painters and his track looks great ( like all of his layout). Just wondering if I am doing something wrong. Thanks in advance for any help.
