Yea Terry, I kinda answered my own question anyways, when I went and sprayed the props RLM 70... Obviously not the color of the main camo....
As far as the lead in the mech pencil goes, standard crap graphite... With sandpaper get the chisel tip.... After hitting the line, use a gummy eraser and go horizontally over the line.... Im real happy with how stong/unstrong they came out actually....
Thanks Crotal, keep in mind this is only my 5th model....
