Modern car paints, driven by environmental rules and consumer demand, are tougher than ever. This shift challenges traditional hand tools and abrasives used in collision repair. The increasing use of low-VOC (volatile organic compound) paints, as reported by Globe Newswire, further complicates the process. This change necessitates that auto body shops adapt their tooling and sourcing strategies. This article explores the evolution of car paint and its impact on the tools and abrasives used in repair shops, examining where these shops acquire their necessary supplies.
The Evolution of Automotive Paint and Abrasives
The transition to low-VOC paints, mandated by the Federal Clean Air Act to reduce harmful emissions, has significantly impacted the hardness and scratch resistance of car finishes. This shift forces technicians to reconsider their abrasive tool choices. Nolan McGannon, a technician at Pet Auto Body in Calgary, Alberta, told Autobody News that modern paints require a modified approach to surface preparation. While the quality of familiar abrasives like Scotch-Brite remains consistent, their effectiveness has changed, often requiring more material to achieve the desired result.
Modern Solutions for Modern Paints
3M, renowned for its abrasive products like Scotch-Brite, recognizes the challenges posed by new paint technologies. Instead of simply modifying existing products, 3M developed innovative abrasive solutions like Cubitron II. Jason Scharton, Global Industry Relations Leader at 3M, and Dan Wittek, Global Application Engineering Director, explained to Autobody News that modern clear coats require a different approach.
Scotch-Brite, a non-woven abrasive, excels at removing material without deep scratches, making it ideal for prepping panels for refinishing. However, its linear scratch pattern can leave permanent marks on modern finishes with fine metallics and pearls. Wittek recommends a multi-step process, starting with Scotch-Brite for hard-to-reach areas, followed by machine sanding with Cubitron II and an interface pad for larger surfaces. This preserves the factory orange peel texture while achieving the necessary surface preparation.
Sourcing Tools and Abrasives: Where Do Shops Buy?
Car repair shops source their tools and abrasives from various suppliers, including:
- Traditional Automotive Parts Distributors: Companies like NAPA Auto Parts, AutoZone, and Advance Auto Parts offer a wide selection of tools and abrasives.
- Specialty Tool and Abrasive Suppliers: Businesses focusing specifically on collision repair tools and materials, often carrying specialized products from manufacturers like 3M.
- Industrial Supply Companies: Larger suppliers like Grainger and McMaster-Carr cater to various industries, including automotive repair, offering a comprehensive range of tools and abrasives.
- Direct from Manufacturers: Some manufacturers, like 3M, allow shops to purchase directly, ensuring access to the latest technologies and potentially better pricing.
- Online Retailers: E-commerce platforms like Amazon and eBay provide access to a vast array of tools and abrasives from various sellers.
The Future of Abrasives in Car Repair
3M’s ongoing collaboration with scientists, OEMs, and paint manufacturers drives the development of cutting-edge abrasives. The creation of ultra-fine grit sanding materials, requiring advanced high-heat kilns, exemplifies this commitment to innovation. While these advancements represent higher initial costs, their efficiency allows technicians to complete tasks faster, ultimately saving shops money through increased productivity.
The evolution of car paint technology necessitates a continuous adaptation in the tools and abrasives used for repair. By understanding these changes and sourcing the right materials from reputable suppliers, car repair shops can maintain efficiency and deliver high-quality results.
