- The resin is designed to maintain its properties at lower temperatures; however, we recommend applying the product at temperatures of 40°F (4°C) or above for best results.
- Proper curing requires strong, direct UV light. Natural sunlight is ideal for this process.
- If sunlight is not available, a UV light source is required to ensure the resin bonds correctly to the glass. We recommend using a UV light with an output range of 315 nm – 405 nm.
- Please note that curing may be more challenging on non-automotive glass surfaces, such as home windows, due to their vertical positioning and reduced exposure to direct sunlight.
- For optimal performance, always apply the product in conditions where adequate UV exposure is available.
