Warming the Glass
When performing repairs in cold weather, be sure to warm the glass and remove any moisture from the repair. The optimal glass temperature range is between 70 to 100 degrees Fahrenheit, and Delta Kits recommends keeping your resin temperature within 10 degrees of the glass temperature, so when doing repairs in the 35 to 70 degree range, be aware that it may take longer for the resin to flow into tight star breaks and cracks. The best practice is to warm the glass and the resin to the optimal temperature range whenever possible. Ideally bringing the vehicle indoors is best but not always practical. Using the vehicle’s defrost and a hair dryer to warm the outside of the glass are also good options.
Make sure to check for moisture. Carefully flex the break with your probe and look for moisture movement. If there is water within the break it must be removed for a successful repair. Removing the moisture from a break takes as little as 20 seconds using a Delta Kits moisture evaporator and the glass can be returned to ambient temperature in as few as 60 seconds using the Delta Kits heat exchanger. The tutorial video below explains how to check for moisture in rock chip damage and demonstrates how to properly remove the moisture before executing a repair.
