The crack in your windscreen that was once a small chip appears to be spreading,
but you still have a good view of the road ahead so you decide that it doesn't
need fixing yet. But keep in mind that chips and cracks can weaken a windscreen
and can obscure a driver's view of the road.
On modern vehicles, windscreens play a key role in the overall structural
strength of a car. A damaged windscreen could lessen the ability of the
windscreen to protect the vehicle's occupants in a collision or rollover
accident.
Chipped or cracked windscreens can often be repaired. There is an Australian
Standard for windscreens, which specifies the size, type and location of damage,
which can be repaired safely.
A sandblasted windscreen also cannot be repaired. Sandblasting appears as
diamond-like sparkles that can reflect the sun or on-coming headlights into your
eyes.
If you do have a chip or crack in your windscreen, it's best to repair when it
first happens, or it could start to spread. Chips and cracks left for too long
can collect dirt and moisture, which makes them more difficult to repair and
more noticeable.
To repair a windscreen, a vacuum method is used to draw out air from the damaged
area, which is then injected with an acrylic resin. Once set, the resin has a
similar strength and transparency to the glass.
The larger the size and the greater the number of windscreen repairs you have,
the more potential there is for light distortion, impaired vision and driver
distractions. Sometimes it's best to simply have the windscreen replaced.
If you decide on replacement, make sure you see a specialist to ensure the
windscreen meets the highest safety standards.
