Cool World S900 Series Security Tint 4mil Thick - RM350.00 WHOLE CAR is a security tint right? or does it make the car tempearture also cool? is i dark? is it JPJ approved? i have a forte, how much for the full car?

Just came back from Cool World Damansara Uptown, Mr Aun the manager there was quite good and his installers are fast and good, I watched them installing the tint the whole time. Workmanship is quite good if not very good, as for the tint I have to wait a few weeks to judge it.
My only concern was that the installers where drinking beer half way to the installation, for me I don't mind much but I think they should wait to finish my car before they drink.
