can someone explain to me, 2mil , 4mil or 8mil , which is better? the thicker the better or the other way around?

but would it cause any problem to smart tag?

Now, thinking to get Raytech, Vkool or Ecotint..hmm... which one is better? Any suggestion?

think this thread is kinda dead..anyway, I'm using Ecotint and i'm very pleased with it.. just got it a month ago with one of the forum member here.. the service given is superb.. and the sales assistants are pretty too..

Ecotint compare to my previous Air-Cool, Ecotint hands down..but off course the Ecotint that I installed in my new car cost lots more with my Air-Cool..so can't really compare..haha..

if my understand is correct, security film is good for security purpose, and not good in blocking heat..so lots of people combine both together..
