Just wanted to share my experience with Windshield Experts, Bangalore and Windshield World, Bangalore.
A couple of weeks ago while on the NICE highway to work, a stone hit my Ecosport's front windshield, thanks to the monster tires of the XUV5OO (no offence to the XUV5OO owners though). A chip, shaped like a clover leaf was the result of it with a very minor (approx 2mm wide) crack on the outer layer. Earlier this week, I noticed that the chip was spreading very slowly and leaving behind tiny broken pieces, I'm guessing due to the flexing as a result of driving on bad patches of roads. The size grew from about 3X3mm to about 5X5mm. Decided to get it fixed and fixed an appointment online for today morning with WSE Basavanagudi branch. Got no confirmation whatsoever about the appointment. Waited an hour and then called them up. I was asked to drop in at 9.30 in the morning and as I did this morning.
I reached 15 minutes early and waited. Doors opened by 9.30 but I was asked to wait longer for their experts and for one of the people I had spoken with, yesterday. After another 30 minutes, they came in, took a 10 second look at my windshield and told me that it could not be fixed and needs a replacement. The reason was that their technique involved a micro drill and the drill would result in the cracks radiating from the chip and that the chip had already developed. I was quoted 7350/- for the replacement as I did not want to lose the NCB on my Insurance. Also, the glass they had was Asahi and not Saint Gobain. They put their transparent printed business sticker on both sides of the glass and told me that it should not create a problem for a couple of weeks to a month until the cracks grow and the glass would have to be replaced. Funny thing is, it was a regular sticker like the ones they stick on headlamp clusters for branding, and I was told that these stickers will prevent the cracks from increasing for up to a month.

I was obviously not very convinced with the response and decided to go for a second opinion.
Went to Windshield World at Electronic City, which I had noticed several times on my way to work. There was a technician at the shop who told me that it could be repaired, but not at that branch. He asked me to WhatsApp a couple of pics of the chip to the franchisee owner who sits at BTM Layout branch, so that I get a confirmation from the owner whether it could be done and how much it would cost. Waited for about 30 minutes and called up the owner and he said he hadn't looked at it yet. 5 minutes later, he replied on WhatsApp and told me that it could be repaired. He asked me to drop in at BTM Layout branch within 2 hours.
Dropped in at the BTM Layout branch 45 minutes later. The owner and a couple of their folks looked at it and told me that it could be repaired, but since the chip was big, it would not be completely seamless. They assured me that the cracks will get filled and the chip or the cracks won't increase. Only that the finish will still have a tiny crater in the area. The only other option was to replace the windshield. Decided to go with the repair.
They placed a small channel over the chip, held by a framework and vacuum cups, inserted a resin through that channel using a syringe. Then, they used a tightener in that channel to screw-in and out every couple of minutes to apply pressure over the resin and drive out any air bubbles. They continued this process for about 20 minutes or so. Then the channel was removed and a small transparent film was placed. They lit a matchstick from the inside of the car and heated that area from behind to let the resin expand in the cracks and dry. They let it dry for 5 minutes and the job was done. I was asked not to apply pressure on the chip or put water over it for an hour. They also asked me to clean the area after an hour to remove the residue from the surroundings.
Came home and cleaned it up after about an hour. The chip looks firm and sealed now, just like they promised. I can see and feel a small crater in the area, but it doesn't look like it's going to develop more.
The technician guys could have been better. They accidentally splashed a couple of teeny tiny drops of the resin on the upper part of my bonnet while pushing the syringe, and it seems to have eaten through the factory clear coat. Only noticeable to me though. Also, I expected the guys to clean the full glass before/after doing the job, considering the dirt and dust that had settled on it from yesterday morning (I was scared to wipe, thinking the chip would increase), but they didn't bother cleaning even the area surrounding the chip. These were the only things I was unhappy about.
Overall, the experience was good. I was charged 900 bucks for the filling and got a bill for it with One year warranty on their repair work and assurance of peace. I saved spending 7k at WSE. I think it was the right call to get a second opinion from Windshield World.
If any of you guys have a second thought about the offer from WSE, try getting a second opinion from Windshield World or anyone else who deals with Auto Glass Repair. You might sometimes get lucky, like I did today.

OT:
They were getting started to replace the front windshield of a PY Registered Mercedes ML350, which belonged to the Consulate of Ethiopia, just as I started to leave. The glass had suffered a coconut tree attack. The quote given to the owner/driver of the car was 85k and Insurance was ready to pay some 79k.
85k for the Windshield at a third party vendor?

Methinks that coconut will be cursed at least for a week by the Insurance provider.
