Hi bro, there is no film from any brand that can make your car "not hot" for parking long.  My car is using Raytech CS85, IRR85%, I tested the car just a little bit warm within 1 hour parking under the sun. Still feel great with it.  Although the car is tinted with solar control film, maybe only 5% of heat coming in from window, what do your think if this 5% of  heat is keep coming for 2-3 hours. The heat will trap inside the car and become hotter and hotter. This called "Green House Effect". If you have any device that can suck the heat or hot air out of car while parking. Then, I think your car will be much cooler. Normally, what i do is wind down 2 side windows for 1 inch, of course my car is fitted with door visor, then I feel much cooler when get in the car. However, due to too many robbery case, i'm not doing so now.

From my personal experience, it take only 5 minutes to cool down my car, although I park my car for several hours. Install a great tinted film will give you better result.

Well, logical thinking do you think it is true? It is true only if your car is moving and air con is on. Your air con keep the temperature low for your car cabin. If you install the high quality solar film, you will not feel the heat while driving even for very long time. But parking is different story.

I think about something, all we know when car parking for long, say about 2-3 hours under hot sun, interior cabin sure will heat up gradually. Only which brand of tint can keep the lowest temperature. This is interesting. I think to suggest Raytech tinting, do the experiment on this issue. 

Dear Experts, need your help for the advices,  is Raytech CS 85 for Cerato cost RM 1600.00 including front, rear and windows consider expensive?  If using 3M or HO with equal spec will be exceeded RM1500?
