Stock tips are the standard nozzles which come with a can of
spray paint. They produce a medium flow of paint, with a tendency to cause
overspray. In
graffiti art, stock tips are useful for
blending and
fading colors and initial
outlining (layout), and are not suited for detail work. It is possible to paint a whole graffiti piece with nothing but stock tips, however, and many people
bomb strictly with stock tips.
Stock tips are generally either black or red in color. Any can of spray paint which accepts male tips can use a stock tip, so they're handy to keep around in a pinch. Rustoleum often uses a differently shaped large stock tip, similar in appearance to a German cap. These tips are interchangeable with the smaller type.
