Yellowing or Failing Repairs:   Technicians using resins from other companies often experience repairs that turn yellow or fail and pits that turn powdery or fall out altogether.    These technicians will use very thin resins in their breaks and very thick pit fill resin as recommended by their supplier. Thinned-out resins are not durable, and thicker resins do not have the "flexibility" to handle the expansion and contraction of the glass surface that occurs with changes from hot to cold. The stress of these changes on the resin used in the repair causes it to fail. Using quality resins AND curing them properly is the only way to eliminate these problems.

Weather Problems:   Changing weather conditions can cause the windshield to be very cold, hot or wet, so don't forget to check the windshield before beginning the repair.  Very cool or cold glass will cause resins to thicken and flow less reliably, making repairs more difficult. Windshields that are very hot present two problems: 1) heat expands the glass and repairs done under these conditions are stressed when the glass cools and contracts, pulling away from the repair  2) heat also thins the resins changing the characteristics such as adhesion, cohesion, molecular alignment, clarity, elasticity, etc.  Moisture can be dealt with several ways but the choice of experienced technicians is to use a Drystar chip dryer to completely dry-out a wet break so a perfect repair can be done.

Curing: As hard as it is to believe, some technicians use sunlight to "cure" their repairs.  Repairs cured using sunlight have higher failure rates (and are more noticeable) due to improper curing.  If  you want to do quality repairs you must use a quality curing lamp, your repairs will cure faster, come out stronger and look better. Even though suppliers will claim their lamps are quality units and will cure resin properly, most don't! If the lamp looks like something a child would use to look at a neon poster in the dark or something that you would see at the door of a nightclub when trying to re-enter, that's probably what they were made for, not curing windshield repair resins properly.
