Yes, its the one I used on the Sancho... works like a champ and quite accurate in my opinion. I started by adapting the TK409 template and making it match the curve of the helmet. After that I applyed the weathering to my template file so I just had to cut it out once and now I have a template to use on all my helmets.
Just cut out the yellow, gently tape it to your helmet ... draw on your stripes using the template lightly with pencil, take your template off, and use masking fluid ot mask off the area around it... I do this becase some times the tape can pull up areas where the tape touches the revealed silver through the paint. Better safe then sorry.
One other thing that some folks do who dont have an airbrush but want an even coat for there stripes... use a latex makup sponge and dab on the paint evenly leting it dry between dabs, build it up with 3-4 coats. Looks great and works for the subtle orange gradient on the last 3 squares as well.
