As a paid intern, Sarah Slavik knows her way around PPG in Oakwood, but Tuesday’s tour with fellow Flowery Branch High School students was still appreciated. “I’ve learned a lot of stuff here from people here,” said the 18-year-old senior. “I can tell you almost every single name (of employees).” She toured the paint manufacturing and distribution plant off W White Road with about 25 science, technology, engineering and math students as part of the PPG’s observance of National Manufacturing Day.
