Custom Glue Formula Specifically Designed for Maximum Bond with Tires Super-Fast and Crystal Clear Drying Maximum Strength Bond - 3,200 PSI Holding Strength Unique Super Soft Round Bottle for Optimum Feel and Stability Re-Usable Snap Fit Yellow Pro-Bond Applicator Tips Overview This is Pro-Line's Tire Glue. Pro-Line knows tires and understands that the strongest bond possible between the Tire and Wheel is a critical aspect of performance and tire longevity. Pro-Line engineers have developed the Best Tire Gluing System ever devised with the specific needs of RC users in mind - Pro-Line Tire Glue. The first challenge was developing the strongest glue possible while also having the correct flow characteristics and dry time that RC Racers and Bashers desire. Pro-Line's new Tire Glue has a Hold Strength of 3,200 PSI (Test Method: Steel on Steel in Tensile Shear) which is the highest Strength of any Tire Glue available. Pro-Line's unique glue formula also provides the fastest drying glue possible while drying crystal clear with no yellowing or whitening found when gluing tires with other glues. The Pro-Line development team did not just stop with improving the glue. Pro-Line Engineers began the design process with the clear goal of revolutionizing the Glue Delivery System (Bottle and Applicator Tip). The Pro-Line Tire Glue features a super soft and squeezable Round Bottle that improves feel as you apply the glue, with the added benefit of the round bottle being significantly more stable on your pit table when compared to the elliptical shape found in all other glue bottles. The single biggest advancement of the Tire Glue system is the all-new Translucent Yellow P-L Applicator tips. The tips are specifically intended around Pro-Line's Exclusive Round Bottle Design and snap into place for a secure fit while gluing. The P-L Applicator tips are Re-Usable unlike the throw-away tubes and have the perfect size applicator hole for gluing tires. Pro-Line includes 2 P-L Applicator tips with each bottle of P-L Glue for maximum value.
