Size:1 Pack 30 ml Thin Resin Product Details: Thin Resin, Pit Sealer, Thick Resin, Pit Filler, Chip Glue, Chip Adhesive, etc all refer to the same substance, resin. The difference is simply the levels of thickness (viscosity). The thinner it is, the easier it is to inject into the windshield. The thicker it is, the stronger it holds. The best resin for repairing a windshield chip or crack is not too thin, but not to thick. That's why our preferred resin is this bottle of Clearshield Thin Resin. It's thin, making it easy to inject into the break, but thick enough for restore the windshield to it's previous strength (and a little bit more). After you've injected the thin resin into the chip or crack, then a thicker resin (we call it pit sealer), can be used where the resin was injected to "seal" the repair. If your goal is to have an easy to inject resin that does the job at a quality level, then we know you'll be satisfied with this resin. This resin bottle also comes with a dropper cap, making it easy to drip small amounts of resin into your bridge or injector. Dropper caps also keep the resin from spilling, saving you money and keeping your equipment clean. For those who know what they are looking for, the viscosity of this resin is around 20 cps.
