I did on my S4 and prior car, 1989 Porsche 928 S4.
Here in Dallas it appreciably reduced interior temps in summer. Barely visible unless you really look for it. I never had anyone notice it unless I specifically pointed it out, damned near 100% optically clear.
Dont remember specifics but it blocked something like 70% of UV and IR
