    Product worked like it was supposed to. It was very easy to use as long as you follow the directions. I think it fixed my car windshield pretty well. A nice product.

    Amazing repair kit

    Posted by Diego U. on 6th Jun 2019

    This product works great! I actually had a double hit by a rock, so had two joining "stars" to fix. Following the easy to understand instructions, I had repaired my windshield in about 30 minutes. Honestly, only I can tell I ever had windshield damage. My 2018 Prius looks new again and that is important to me since it is only 2 months old.

    Actually this product is over my expectation. as it can be seen, after using this product three times, the windshield looks like before! it's hard to see the trace. I have to say it's really worth to get one!
