I've been repairing windshields for 15 years and I've learned it is best to prepare a customer for the worst then when the repair comes out good they are very happy. Tell them that theres alot of damage and it is a difficult repair but you will do your best. I always tell them it will clear 90 to 95 percent that opens up the thought process that it's not going to go away completely, I explain light refractiveness, the prizm effect once you've done this you will rarely get complaints. Then you have the last one you do for the day the guy looks like he doesn't have much money so you do him a favor and discount your repair he will complain about everything, avoid doing favors they will bite back every repair should professional and priced accordingly: I hope this helps Dave
