This ultra-thin resin has excellent flow properties to fill the most stubborn breaks. The package design lets you dispense a single application per break, making syringes and needles obsolete. It also eliminates the guesswork of inventory control with bottled resin. Unlike our other resins, the Extreme formula is available exclusively in single shot format. Cures non-yellowing, optically clear. 25 single shot dispensers per UV-resistant package. Mylar squares are required for curing (HDW3000, sold separately).
