You may be wondering, why is the rear windscreen the most important to tint? Why isn't it the front windscreen?
After all, we face the front windscreen the most and the largest portion of the heat comes from the front side.
If you’re thinking because of the goods you store at the back needing privacy, you're far off.

Do you notice on many cars, the bubbles are always formed on the rear windscreen?
You don’t see too many tint bubbles forming on the side windows or even the front. Ever wondered why?
It is because the rear windscreen has higher chances of forming bubbles. Bubbles form on the rear windscreen because of a few reasons.
Most of the time, the bubbles are formed due to the heater line or the demister.
The heater line runs heat onto the rear windscreen preventing fogging for you to see clearly especially in the morning.
It is a feature built-in to most cars especially on those without rear wipers.
But if you forget to turn off the heater, the heat will continue to be there throughout the day. This will cause the tint to expand after a long exposure of concentrated heat on the lines.

How do we avoid this? Firstly, remember to turn off the heater when not in use.
This will prevent the heater from overheating the tint for a long period of time. Another way is to install a good quality tint especially for your rear windscreen.
This is important because for other windows, the tint can easily be replaced. However, for the rear windscreen, replacing the tint runs a risk of damaging the heater lines.
If the tint quality previously installed is of poor quality, it will be difficult to remove the old tint to replace them.
Removing it completely without damaging the heater line takes a lot of skill and time, but the risk of breaking the heater is always there.
What happens if you break the heater line? Most of the time, replacing the heater line is difficult and not encouraged.
If this happens, you may have to replace the entire rear windscreen. This is a hassle even if you are covered by windscreen insurance.
It takes time and you will still have to retint your rear windscreen and run the risk of it forming bubbles again if a bad tint is installed.
In conclusion, the tint you have to take care the most, and prioritize installing a good quality tint on, is the rear windscreen.
Getting a good tint helps to prevent bubble forming and ultimately saves you a lot of hassle on replacing tint or even the windscreen.
