In the mid-1990s, a pivotal meeting occurred between Larry Rubin, grandson of Testrite founder Herman Neuwirth, and Dan Guirl, grandson of GAT Systems founder Howard Guirl.
This connection proved instrumental when Testrite Visual, a respected manufacturer, decided to revolutionize its powder coating operations. Rather than continuing to outsource, Testrite made the strategic decision to bring this crucial aspect of their business in-house, a move spearheaded by GAT Systems and their local rep firm, Slocum Equipment, guiding Testrite Visual from initial concept to full implementation.
