I hand lettered this 1949 Ford F-6 today, and gave it 50 years worth of wear. There is only one way to produce realistic aged lettering, and that is to hand letter it. Almost every time that I see "faked" old lettering, it's sprayed through a stencil and buffed off in random spots. This is not how lettering ages. Old hand lettering fades in the strokes, and is very directional. This can't be duplicated in a sprayed field. I have studied and geeked out on old faded lettering for years. It's a real joy to produce lettering that is very believable.
