This product’s journey from last year’s mediocre performance to today’s standout capability demonstrates the real difference thorough testing can make. Having taken both these resins through real-world cracks and chips, I’ve seen how crucial strength, clarity, and ease of use truly are. The Clearshield Windshield Repair Resin 30ml impressed me with its 3,400 PSI strength and Shore Hardness of 80D—meaning it holds up under harsh conditions and won’t crack easily again.
What sealed the deal was how smoothly it dried—no bubbles or chunks, just a crystal-clear finish that blends seamlessly. It’s long-lasting too, preventing re-cracks over time. Compared to DiamondClear’s similar viscosity and UV resistance, the Clearshield resin offers better durability and a more consistent pour, giving me confidence for multiple repairs. After testing both, I can honestly say this product provides the best combination of strength, clarity, and value. Trust me, it’s the one I’d reach for for a professional-quality fix every time.
