dreamy> edz, for that type of film, at night when you on your lights, everyone can see what you do man, unless you go for heavy tint.
best choice is still curtain to cover up for privacy, IMO.
my current unit also got paste those type of sticker but it's not the tinted or solar type. it's just the blurry type which i cannot see outside and outside cannot look in. Yes, it will shrink even though we get a bit of sunlinght only.
still got a lot to learn about all these reno tips.
