Here’s a quick comparison between a single 1/4-inch pane of glass and that same pane of glass treated to two of the company’s latest offerings, FX Premium and Crystalline automotive window film.
VLT (or visible light transmitted)
The percentage of visible light that
passes directly through the filmed
glass. The higher the number, the
lighter the film.
UV Rejection
The percentage of ultraviolet light that
is repelled by filmed glass. Ultraviolet
light contributes to sunburn and other
harmful skin conditions from the
sun and to the fading of fabrics and
leather.
Solar Energy Rejected
The percentage of total solar energy
rejected by filmed glass. The higher
this value, the less solar heat energy
is transmitted by the glass.

With the side glass lowered...

With the side glass lowered halfway, you can see the slight difference that the Crystalline 70 yields in the visible light spectrum.

This front and rear shot shows...

This front and rear shot shows the difference between the windshield, which is untreated, aftermarket glass, versus the Crystalline 70 on the side and back glass. I’m not a fan of tinted glass (other than the factory ’50s green tint) on classic trucks, but the smoked look of the 70 really looks nice.

Keep in mind, however, that the law changes from state to state as far as how dark one can go. Most states allow up to 70 percent VLT on the front door glass, while any darkness can be used for the rear doors and back glass. That makes using the Crystalline 70 on both doors and that big window out back perfectly legal on old trucks, and that’s just what I did. After talking with the folks at 3M regarding the product that was available and most logical for the vintage truck crowd, they turned me on to Ryan Tounsley and his company Protective Film Solutions. Ryan educated me further in all aspects of the automotive window film world and I have to admit I was quite impressed by the vast options available to automobile enthusiasts.
We decided to go with the Crystalline 70 film on the side glass and back window for the ’68 to keep the appearance relatively original, with a slight tint. A lot of our old trucks had “tinted” glass from the factory, be it slightly green or smoked, and I found that the Crystalline actually accentuated the factory tint nicely. But it’s really the end results in the creature comfort category that had us impressed. The following weekend after Angel Diaz tinted the truck, I headed out to Anaheim, California, for the F-100 West Coast Nationals.
It was a pretty warm day and the sun was beating down on us unmercifully on the ride out and back. Usually, at highway speeds at this time of year, I’d have the A/C cranked up full blast, but with the new window treatment, I could actually turn it down quite a bit and still be comfortable. That was enough to make me a believer, but the radiant heat that used to be present coming through the glass is also remarkably lower, making the truck truly comfortable driving down the highway even when the sun is beating straight through the glass.
So if you’re suffering from the summertime blues thanks to sweltering temperatures inside and outside of your classic truck, take a ride to your local 3M-certified installer and see for yourself the difference a little tint job’ll do!
I decided to put my temperature gun to the test before and after the truck got tinted. Pretty impressive results and the numbers speak for themselves. Here are the results:
