I spent over 5 years as a contortionist, keeping my left arm out of the sun when heading S in the A.M. & N in the P.M., along w/ slipping a manila envelope under my pant leg (whilst wearing shorts, of course) to keep upper leg from getting sun overexposure.
Then it hit me; window tinting!!! So I decided I'd splurge with my new truck, and get the two side windows done & an 8.5" strip across top of windshield.
Problem is, the green safety book specifies no less than 70% of light can go through commercial vehicle window tinting.
Question: Is a 30% reduction enough to be effective? Anyone try 70% on their truck?
Thanks for your help!
