I'm having doubts on the selection below

Front/Back
1. 3M Crystalline
2. Vkool Elite

Sides
1. 3M Nano
2. Vkool Safety 4mil/Vkool Premier 6mil

As i heard common from 3M users are that SmartTag / GPS related devices signal are affected after installation and would require a small section to be cut off in order to allow the signal to passthrough. Is that right ?

for security films, is 4mil the safety point for our windows ? as I'm concerned about the thickness would affect the window motor in the future if we were to go beyond that (e.g. 6mil vkool premier). Not to mention heat rejection on security films are not as good either

Hope someone could shed some light here

previously using vElite front screen on my old car.. now using HO's Sech60 but heat rejection is still more or less the same, the hue looks better on HO though

i'm using C40 on the sides .. very pleased with the performance just the front is annoying

anyone can recommend installation place for 3M/Huper Optik in PJ area ?

I was looking into ceramic films from 3M, Huper Optik and XPEL. If based on TSER% XPEL would be the highest among the bunch not to mention the most expensive too. But how are we to make sure these figures are not cooked up ?

My priority would be to have a better heat rejection
