Will the car film hurt the car glass?

Objectively speaking, it can't hurt the glass, but if it is some isolated glass, it will be heated when it is pasted. Because some construction workers are not skilled enough, there is a danger of glass bursting, but the probability of this happening is very small. Even if it happens, it doesn't matter. The builder will be responsible for compensating you, so you'd better go to the 4S shop and ask for a replacement. Other places are not original.

As for the price, I don't know where you are, because Johnson & Johnson sells in different regions, and the price varies from place to place, but the gap is about 300-500. Take Guangzhou as an example, the whole car is attached to 1.800 yuan. Please remember that there are many counterfeit goods on the market now. It is recommended to choose Johnson & Johnson store to post it, so that it can be guaranteed.

If you want good heat insulation effect, of course, the whole vehicle is suitable.
