5.What’s the repair efficiency? Won’t it be a heavy waste of time to change the grinding sheet? Do you have any more efficient products?

1. This kit can repair a 5 cm long general scratch in 3–5 minutes.
2. The grinding sheet and tray both adopting magic tape are easy to change. To repair shadow scratches needs 2# grinding sheet and the polishing pad; to repair serious scratches needs 1# grinding sheet for fine grinding, 2# grinding sheet for coarse grinding, and the polishing pad. They both are simple and quick.
3.We are still working on a simpler and more efficient glass scratch repair kit which will use a kind of material excellent both in grinding and in polishing. Quick grinding requires many large particles and quick polishing requires fine grinding. To find such a material, we need keep testing. Our technical department is working in this direction. Let’s look forward to a new breakthrough!
