Fusion Process

Experience Fusion

According to surveys, the #1 reason people wash their car is because it makes them feel good. Delivering an exceptional experience in the tunnel is a critical element in creating that “feel good” feeling. However, this is only the beginning. The key to retaining customers and maintaining a premium average ticket requires a noticeable difference in the quality of the vehicle. The Fusion Process is the industry's first integrated combination of chemistry and equipment designed to create a long lasting shine that brings customers back again and again.
