Sputter is metallic based and more effective in rejecting heat, but will cut Infra signal resulting RFID Card/Smart tag hard to detect.

Ceramic usually lower in heat rejection thus no issue with transmitting Infrared tech signal.

Popular choice are 3M Crystalline Films which is high in heat rejection but will be a little difficulties using infrared transmitted device.

currently I am using IrisPro the one with 100% UV rejection, doing good so far for 1 year half

Raytech I had on my other car feel meh.. but I took FX series which is entry-mid range, but it still wasn't cheap

Just have to make sure getting the authentic one from 3M Authorized Installer.
Because we as user do not have proper tools to measure if tint used are authentic, even with the meter they use to measure, any cheap tint when it is new the number will be good, what I care more are how long the tint can last before it degraded.

UVpro series I go for VTL 30 side and rear then 50 for windscreen.

After 1.5 years still satisfied like new, but my car parked at basement carpark, that could be one of the factor slowing the degradation

They have a meter to measure, but if it is 100% or not my eye can't tell that and I have nothing to prove

They have other lower end series that is 99% UV 380nm which measure UV able to went through more if using UV420 grade meter, while UVPro90 series able to shown block 100% at meter.

The point they trying to make is usually tinted 99% UV rejection were measure with <380nm grade meter
Theirs were measured with 420nm grade which is higher grade and although higher grade it still score 100% rejection.

But in the end of the day it is their meter that they are using, no one knows if it was rigged.
