There are several pin stripers with shops in SoCal. Dennis Jones in Whittier, CA who has been doing it for 47 years freehand pinstriped my truck. There is usually a group of pin stripers setup at the larger car shows -Goodguys, Grand National Roadster Show, etc. Also, post your question on the HAMB. You might have better luck over there locating a striper that’s close to you.Is this a lost art? IsTheir still some strippers around?
Every July at the Syracuse Nationals Car Show, they have a building where pinstripers do their thing for charity. http://www.artiesparty.com/
