The 3M 4904 reinforcement patch is engineered for backside repair of automotive plastic components, providing strong structural support for damaged bumpers, fascia, and similar parts. Its thin, flexible gauze laminate conforms easily to curved surfaces and helps prevent bulging during adhesive application. The open weave design absorbs repair adhesive quickly, making it suitable for fast curing products with limited working time. An integrated plastic release liner allows precise placement without contacting wet adhesive. Measuring 5 inches wide and 12 feet long, this patch offers ample coverage for multiple repairs and is a dependable choice for professional body shops and dedicated DIY users.
