I have a 2013 S4. I want to get window tint. Does metal tint interfere with anything.

What should I go with

Metal - $150
Carbon - $289
Ceramic - $399

Is there anything I should ask or look out for?

 

I was told that the metal films interfere with the FM and AM stations on the radio. Plus the Ceramic film is best for heat rejection. I just got mine done at Tint King. got the FormulaOne Pinnacle for my S4 wagon. Came out great
