Hardline International Inc. has been a leader in the tire and wheel industry since 1980, building a reputation for innovation and adaptability. Originally focused on manufacturing tire liners, the company evolved alongside industry changes, diversifying its operations as tubeless tire technology became more prevalent. A major milestone came in 1989 with the acquisition of Inventamation, securing all rights and patents to the groundbreaking RIMM-KLEEN single wheel blaster and setting the foundation for future growth.

Following this acquisition, Hardline International expanded the RIMM-KLEEN product line by developing a complete rim refinishing system that adapted to changing paint technologies. From early baking enamel and air-dry coatings to modern powder coating solutions, the company has consistently refined its systems to deliver durability, efficiency, and superior performance. Today, Hardline International continues to advance RIMM-KLEEN Systems, remaining a trusted provider of high-quality powder coating solutions for the rim and wheel industry.
