I got a windshield crack / star, in size of a smallest coin. After reading here on google I decided to get it professionally repaired instead of doing it myself.
I paid $45 at a local professional auto glass repair shop. It took them couple of minutes to do the job. All the legs of the star were filled with glue. The center of the stare has a rough surface so the repair is easily noticeable. This is my disappointment number one. They did not use any UV lamp.
This morning, I noticed that the star is growing. Last night was warm without any large changes in temperature. This is a disappointment number two.
Replacement of the windshield is $350. One repair is $45. So after about 8 repairs you paid of one windshield. Next time I buy do it yourself glass repair kit, which is only $7. For $14 you can get a kit for multiple repairs.
The only warranty I received with the repair is that if the crack progresses and I decide to replace a windshield at their facility they give me $45 discount. Thanks a lot!
