Another thing on my to-do list is to have 3M Crystalline film applied to my windows.

Even though the Griffiths A/C works well, it does not take long for a black car sitting in the full sun here to turn into an oven.
I see a few benefits to Crystalline:
1) It helps protect the interior from harmful UV rays. I have an original dash that isn't cracked. I'd like to keep it that way. Helps preserve the interior and prevents my legs from getting scorched by hot leather seats.
2) Helping to keep the temps down when the car is parked in the full sun. That just means less work for the A/C to do once the car is started.
3) Helping to maintain cabin temps and comfort. Sometimes when I'm driving the sun is just blasting away. Even though the A/C is keeping me comfortable, there are places like the dash and trim on the doors that are still hot to the touch.
