Many will keep ledgers or records of their activities, including where they tagged and how long the graffiti stayed up before it was removed. Some will travel to other areas to learn about graffiti techniques. They also study the work of other taggers , often from other areas around the world. Of course, the Internet has only facilitated this process. They will take their friends to see it.
Taggers often test different types of paint to determine which types are most effective.
They choose colors for intensity and coverage, not to reflect group affiliation. They also alter spray nozzle tips from household products to create different spray styles. Underground magazines, newsletters, and Internet e-zines publish photos of tagging hits from across the country, and offer ideas of how to create similar art pieces. These magazines may also publish advertisements for special supplies, clothing, and instructional videos. Taggers access the Internet to share information with other taggers around the world on tagging techniques, product preferences, and magazines.
