I was very thankful for their installation several years ago...until a crack appeared mysteriously in the upper center area of the glass a few years later. Safelite in NY replace it and they told me that when aok scraped the old adhesive away pre installation and scraped the paint away (which happens and is acceptable according to the safelite guy). One problem was that aok did not put an adequate amount of primer down and now there is an impressive amount of rust formed from these scrapes aok made. What caused the crack in my windshield according to safelite was the uneven distribution of new adhesive to hold the new windshield in place. The crack formed because of this according to safelite. I took pictures and sent to aok. The manager told me I couldn't prove they did this...end of story.
