Ordered/Installed: Perforated White One Way Overlay
 

this is not printed so will be white. should have extra so if someone else wants to give it a shot I can send some your way. I just ask you to use it and not set it on a shelf. will see if this keeps me a little cooler on the drive home. will last a few years. plan to use on back window but might also try on the sides. only concern is the rear facing DVR.

How much would I need to cover my car? :)

What a brilliant idea! Keep us updated if this keeps the interior temperature lower. If so, I'll order some right away!

Xist -- If the windows are ≤26" you'd have 10 feet. If you have thick C-pillars or you can overlap the side window pieces you might get the side windows and backlight out of a full sheet.

not shipped yet but Estimated delivery Fri, Jul 17 - Fri, Jul 24. the 26th i will be heading out of town, to Kindersley, SK. CA. will be gone 3 weeks. might not be able to give impressions till i get back if it's here the 26th. coming from NY.

Why not just use window tint?

double it? i already have tint. this goes on the outside.

Interesting. Would you have more visibility with illegal tint instead?

Laws are weird...

won't know until i try it. i have legal on the back so that will be a good gauge.

This stuff is only legal on windows that don't have a tint limit (rear and rear side windows), that is you could just go to a darker tint for a similar effect. It's not away around tint laws.

Looking at the pics it looks like about 40% light transmittance. If you add this over 40% transmittance tint, you'll have roughly the same effect as if you'd just gone with 15% transmittance tint.

Although the white colour is good for reflecting light, tint films have metallic particles added which serve a similar purpose.

Unfortunately it's going to be a hard thing to test properly unless you have two identical cars.
