Prestone Heavy Duty Aftermarket kicks off every year at Heavy Duty Aftermarket Week (HDAW)! HDAW is the largest North American gathering of heavy duty aftermarket professionals in the industry! HDAW is a great experience for Prestone to meet with customers and have them learn more about our products and learn what is going on in our industry. Every year Prestone hosts one-on-one business meetings, with key customers and new opportunities. The one-on-one meetings are focused business meetings off of the Product Expo floor. Each one proves to be successful. The A Product Expo, offers an exclusive view of all the products Prestone has to offer in the heavy duty aftermarket. It has been a great source to communicate the OEM approvals on our Command antifreeze products!
