Looked on Craigslist and FB Marketplace, Google too. Found places that will repair chips but nobody does cracks. There are plenty of youtube videos from companies that do it like, https://www.youtube.com/watch?v=XT6vdB4Kczg and https://www.youtube.com/watch?v=0jr9Gojvt6E so it's seems like it would be profitable. I have a semi-professional kit that does chips and I may have to modify it for the crack, but would prefer someone with experience to do it.
