Something I'm not sure about.

Ok I did my xj in Monstaliner and am thinking about spraying some military stencils on. How would I go about making it look old?

All ideas welcome.

Paint color could go a long ways here, choosing a beige or light gray for instance would look like an old white.

I'd also lean towards an "amateur" job. Just not doing prep work, not even washing it, could cause just the right amount of paint to stick.

Depending on the look but oranges yellows browns blacks along the edge using a small airbrush. Can make about any look you want. I would use offwhite for the basecoat of lettering. Also u tube airbrushing effects should give you some ideas. Some real awesome tutorials out there. Guessing this is going on the od green jeep right?
