I am using my car in the coastal region of India, where the temperatures go up to 47 degrees centigrade with a humidity of 80%, in the summer days it will be very hot and when i come to office in my car and park, by afternoon the car gets very hot and it takes about 4-5 minutes to cool down the car with full AC on. For this are there any heat resistant paints which can be applied on the inner roof and the inner walls of the doors of the car, so that the car interior temperature does not go up. Also are there any alternate solutions for resisting the heat to enter the car.
