“I don’t want people to remember my car,” Ms. Condelee said. “I wanted a cool car but not a car that could be traced back to my house, because people are crazy.”

Ms. N oland learned how to wrap cars by watching hours of YouTube videos. She uses basic tools for her creations: X-ACTO knives to cut around door handles and roller brushes for larger paint jobs. “I’m still learning, so I definitely don’t want to mess up anyone’s investment,” she said. “For many of these people, it’s the most expensive thing they own.”

“Especially in L.A., people are in their cars all day, and it’s joyless,” she added. With her wraps, “they had permission to be a little absurd.”

Ms. Condelee decided to give it a try after watching Ms. Noland’s YouTube show. “I wanted my car done, but I didn’t want it to be outrageous,” she said. “Peggy is extreme, she’s furs and hearts and big stuff.”

Ms. Noland ended up wrapping the car in a silvery rainbow acrylic. “The bumper is offset, and on the side the paint was already a little warped before she put the vinyl on, so there’s a little wavy spot, but I don’t care,” Ms. Condelee said about the results. “Teenagers think it’s cool.”
