Our 90 resin is the same formula as the 45, it can be used for all stone-breaks with the Wonder Bar Bridge and as a point resin for long cracks. Use for bullseyes, stars, or combination breaks with extended legs. Works fastest when the windshield is 65 degrees F or above. Can be used in the first couple of inches at the point of a short crack or a floater crack. Exceeds the Repair of Laminated Auto Glass Standard (ROLAGS) requirements. Like all of our resins it is moisture resistant. Temperture resistance is - 30 (below zero) F to 250 F.
