I suspect that there is still a small chance that this will develop into a bigger problem if not treated?
It might. It might not.
There are many variables to list and the probable outcomes are as diverse. As long as you can see through those adverts which tell you that there is never a good time to have a stonechipped windscreen...
In the winter, the cold weather (??) might turn that tiny little chip into a great big crack costing you your EXPENSIVE excess; your kids will go hungry and you will no longer have enough money left to take them on holiday when they break up from school.
The Summer! Oh yes... whack on your AC and the same thing could happen... only this time that money you were saving for nanna's funeral will have to spent on having China's finest glass put into your car. You won't have any money left to pay the household bills so your house will be repossessed and you will go to prison and will be forced to play mummies and daddies with your new family, Terry and Dave.
Potholes! Don't forget the potholes. Go over one of these and you shouldn't think about complaining to the council for not maintaining our roads, or for paying peanuts to Albanian sub contractors who - if they remember to - will stamp in a bit of asphalt in between tapping up local residents for small building jobs at the weekend.
The fact is, glass is a solid object (well, it's actually a liquid believe it or not). It expands with heat and contracts in cooler temps. Some stonechips will never worsen; some will crackoff immediately and some might even 'snap' through torsional forces ripping through the chassis (that said, if the screen has not been fitted well, it probably will not make the slightest bit of difference). Different chips or types of damage will behave in different ways. The variables *could* be temperature, or it could be in movement, vibration, or a bird's feet pressed up against the glass as she's having a portion stroked into her.
