PPG announced that it achieved a GUINNESS WORLD RECORDS title for the largest simultaneous paint stirring challenge during a customer event at the 2025 SEMA Show in Las Vegas. More than 275 participants stirred paint together to highlight the manual workload still common in collision repair before the company unveiled its SEM Mix’n’Shake automated stirring system.

The Mix’n’Shake system produces a homogenized car paint mix in less than 60 seconds. According to PPG, automating this step can help body shops reduce rework, improve paint consistency and workplace cleanliness, and recover productive work hours. The company also reports that the system can cut sundry costs tied to stirring sticks and disposable cups.

A GUINNESS WORLD RECORDS official verified the participant count and confirmed the record. After the attempt, attendees watched a hands-free demonstration of the Mix’n’Shake system. The paint used during the stirring challenge will be donated to Dixie Technical College in St. George, Utah, to support hands-on learning in automotive and collision repair programs.

“This was more than a record-setting event – it was a symbolic moment for the industry,” said Rodolfo Ramirez, PPG vice president, automotive refinish coatings, Americas. “By showing how much time and effort shops still spend on mixing, we helped our customers see the value of automation.”

Mix’n’Shake is part of a broader PPG effort to support automation and digital integration in body shops. The system connects with the PPG LINQ digital ecosystem and complements tools such as the PPG MOONWALK automated mixing system, which are designed to help shops reduce waste, increase throughput and allow technicians to focus on higher value tasks.

The system will be marketed under PPG’s SEM brand as SEM Mix’n’Shake in the United States, Canada, Australia and New Zealand. It will be sold as PPG Mix’n’Shake in Europe, Middle East and Africa, Latin America and Asia Pacific. Additional information is available at semmixnshake.com.
