Ic, nanoceramic suppose to be able to use smart tag I think
The 1 affect smart tag should be metallic
Means the 388 is not really nanoceramic?
Maybe I'm wrong
No, metallic does not necessarily stop smart tags. As a matter for fact, many high end metallic tints can use smart tag.
It is RFID that are especially susceptible to metallic signal interference, not smart tag.
Smart tag uses a certain range of wave that many tints with very high IRR that uses similar wave affected them.
VKool 70 has issue with smart tag signal but not VKool Elite (front tint that might be using what used to be VK75 or euro spec, not sure now).
3M Crystalline is not smart tag friendly and it is not metallic, it has 200 layers of nano-polyester (mind-bending). So is Raytech best Windscreen clear range Ultra 70 (highest range) that is nano ceramic and yet cannot pass smart tag but their 2nd range nano-ceramic can.
When the IRR is high enuf and using the same wave as smart tag, screwed.
As mentioned VKool Elite with high IRR (not as high as VK70 tho), no issue with smart tag, so is Irispro metallic based tint (highest end with high IRR Diamond X nano-silver/titanium and Diamond nano-titanium range), no issue at all with smart tag (I go thru 7 tolls a day, a mixed of RFID and smart tags), rarely got stuck at smart tag, if any.
From what the IRISPro owner mentioned, they designed the tints using another range of IRR signal wave to avoid complication with smart tag. (whether that is true or not, no idea but as long as it worked great for both heat rejection and smart tag usage, who cares, hahaha).
Do note IRR only takes up half (53%) of heat resistance, since UV is mostly 99% for most good tints (abt 3%), the VLT has the remaining 44%. That adds up to TSER that we should look at.
So VLT darkness is as important as IRR. Those want clear tint especially for JPJ will have no choice but to allow lots of heat thru FWS (70%) and front side (50%).
If you parked a short while or couple of hours under noon sunlight, makes a huge difference to have darker VLT but if you parked whole day, not much of a difference in terms of heat, 15% VLT sunlight will accumulate heat overtime to max vs 70% VLT is sunlight but higher TSER/lower VLT/High IRR just slows down the heat penetration (talking abt heat resistance only).
Now, the protection of dashboard fading, leather seat....that good tints will extend the life much much longer.
Now comes the TSER reading. Even cheap house brand tint can claim 67% TSER vs same TSER of premium tint...you believe that?
Even branded tint TSER calculation sometimes I also doubt.....coz I see higher end tint with TSER 67%, then their own lower end tint also TSER 60++...I also blur..may as well take lower end tint coz also 60+ TSER.
But then when used in real life experience, that premium tint TSER seems to be nearer to as listed but the cheaper one..haiz, some worked as expected...then couple of years, total failure.
So takes TSER with a pinch of salt as well. Sometimes word of mouth or indepth review of existing users matters way more. Better yet, sit in car with the specs you want, see how.
BUT then again....ppl have different expectation, what is great for me in terms of heat resistance might be shit to others that expect higher due to their unique heat tolerance.
For eg. in my house, I feel slightly warm but not hot but yet my wife screaming super hot...I say no way, but then I saw the sweat...wtf....ppl have different heat tolerance...
