Not quite as dark as the factory glass shade in the rear, but close

 

Don't forget. the factory installed option by Porsche - "Thermal IR Glass" for the Panamera and Cayenne's cost $1125 for just the rear windows!

Yet, it does not perform as well as PhotoSync on a relatively cool day at 72 degrees...now imagine if it was hotter. The degree spread would be more significant!

 

PhotoSync does come in the following shades (represented in "VLT" - visible light transmision)

PhotoSync? - Prestige Film Technologies

75%
65%
45%

***Keep in mind, according to the manufacturer, their "Solar Adaptive Coating" is what's truly unique about this nano tint. The performance of this tint actually improves as it gets hotter. Another effect of their Solar Adaptive Coating is that the film actually darkens when the sun gets more intense....by up to 11%! We had confirmed this effect as well.

We have used the various products on the market before such as dyed, metallic, ceramic, & hybrids and so far, this is one product that is technologically advanced to match the technology of luxury cars today.

 

This is a great performing product from your tests! Hope they come out with darker shades though. I could never go for anything lighter than 20%

 

Not likely in the near future according to our representative, but fingers crossed.

 

Here is a different angle shot. PhotoSync45 (45% VLT), 98.5% IR rejection

 

And the more light VLT allowed in, correct? The lower the % the lower the VLT, yes?

 

100% will represent complete transparence. The lower the percentage, the darker the tint gets.

 

With the current heat wave across the country, this would be the perfect addition to any car.

General Specs:

Total Solar Energy Rejection up to 65%
IR (infrared) rejection up to 98.5%
UVA UVB block 99.5%

Per some requests, here is another angle shot.

 

Just some more information to help members here understand better how this nano window film compares to other products out there

The solar spectrum consists of Visible Light (44%), Infrared (53%), and Ultraviolet (3%). Since infrared accounts for 53% of the solar spectrum, the performance of the product in this form of measure is quite important. Most dyed window films on the market only produce infrared rejection of 20%-30%. By comparison, PhotoSync blocks out up to 98.5% of infrared. The uniqueness of this product is that it's infrared rejecting capabilities improve as it gets hotter...

Some of the metallized films on the market will produce some impressive results; however, at the sacrifice of interfering with electronics. PhotoSync uses nano technology to produce significant heat rejection without affecting items like cell phone signals, radar detection signals, am / fm, etc.
