I have a friend here in Ohio that is amazing with freehand pinstriping. He's in the Ashland/Lodi area. Has his own sign shop
www.goldenopportunitysigns.com
Check out his site....he loves to go to car shows and takes his paint box with him and does work on site. He did some awesome cars at a PT Cruiser show and he was at the Columbus Volksfest this summer. He travels to other states too if the show is big enough.
