I have installed film tint on the glass in my house.

of course, the tint film is usually installed on the inside.

however, i have some spare tint film (i bought a roll) and was wondering for extra protection from sun, can (should) i put another layer of tint on the outside as well for the dining windows ?

minimal rain on the outside part....

so if i put a 2nd layer outside (after inside already install 1st layer), ok ke ? cooler kan ? 

hope to get your feedback ...

i bought a roll of tint film, and after installation, there is still spare.

you think its ok to double layer inside ? i didn't think of it........
