How We Started

In 2010, traditional sheet metal spray painting was very polular while the use of a large amount of paint caused pollution, and when a car had a dent, people always went to repair shop to re-spray paint. As a car dent repair expert, our founder Yunliang Yang wanted to change. He found that 80% of car dents can be repaired without damaging the paint, and can be operated by oneself without professional maintenance personnel, so he designed the earliest car dent repair tool and established Super PDR.

We never stopped. In 2016, we found the success rate of glass repair in the world was less than 60% with obvious repair traces left on the glass. Also, the production of windshield requires huge power energy and mineral resources, accompanied by a large Industrial waste - each piece of windshield causes 15KG carbon emissions. Super PDR researched the principle of glass cracks and launched our own car glass repair tool, which will reduce the repair time from 60-180 minutes to 5-30 minutes, the success rate is increased to over 90%, it has become the world's leading auto glass repair tool.
