I had a huge chip talking when he drilled it glass popped out he’s like shit this isn’t gonna fill I’ve never saw one this big I’m positive it won’t work, he filled it filled it some more filled it even more lol and to his surprise it filled. Great guy fast and may have little more confidence that he can fill large “chips” I dnt know what the cost was it went to my insurance I can’t really give any stars but super satisfied with the service. The chip repair is still holding strong
