Question 1

Will this kit fix a crack longer than six inches?**

Accepted Answer

Not reliably. This repair kit is designed for small chips, star breaks, and bulls-eye cracks under 1 inch in diameter. For longer cracks—especially those reaching the windshield edge—we recommend professional repair. Many users on Reddit report that attempting to fix large cracks with DIY kits often causes them to spread further.

Question 2

Does the resin harden fully, or will it stay sticky?**

Accepted Answer

Proper curing requires direct sunlight and temperatures above 60°F (15°C). If applied in cold or cloudy conditions, the resin may remain tacky. Several TikTok users noted that parking in the sun for 2-3 hours after application solved the stickiness issue. For best results, apply on a warm, clear day.

Question 3

How long does the repair actually last?**

Accepted Answer

This is a temporary cosmetic fix, not a permanent structural repair. With proper application, it can last 3–6 months for small chips. However, thermal stress (hot/cold cycles) often causes hidden cracks to reappear. It’s an excellent stopgap until you can visit a professional.

Question 4

The suction cup keeps popping off my curved windshield. What am I doing wrong?**

Accepted Answer

This is a common frustration. First, clean the glass thoroughly with alcohol. Then wet the suction cup slightly before pressing it firmly—this improves grip on curved surfaces. If it still fails, consider a kit like Permatex, which includes a more flexible suction cup. Many users find that applying firm, even pressure for 30 seconds helps.

Question 5

Can I get a refund if the repair fails?**

Accepted Answer

Most sellers on Amazon offer a 30-day return window, but we recommend checking the specific listing’s return policy before purchasing. Since results depend heavily on application conditions (temperature, chip type, glass curvature), some buyers have reported difficulty getting refunds for “user error.” If you’re unsure, start with a single pack—the cost is low enough to test.
