My tint guy says that although people are not suppose to do it, it is a very common request by many people because of the hot Texas sun. My tint guy said he can tint my windshield with the same matching Solar Gard Ultra Premium (UP) 75 clear ceramic tint, but there are some minor warnings: state and registration stickers will have to be carefully removed, they will not be responsible for any tickets (but being 75%, he said it is unlikely because it is hardly noticeable compared to what other people are tinting), and cost.
So far, the tint on the side windows and rear are great. The tint suppose to reflect 99% of uv and 40% of the heat. I believe that coupled with the Volt's E1 windows, it is even more effective. I can barely feel any heat from tinted windows, but there is a slight noticeable heat under the windshield.
But considering that I don't drive that long, and when I park I will use the sun reflectors in the parking lot, I am reconsidering *not* getting the windshield tinted. The main reason is to avoid the hassle of risk ruining the tint each year when I have to get the inspection sticker replaced. Another reason is that the cost is near $200. (which is almost half of what I paid for tinting), and I do not think saving 1-2 mpg in a/c would be worth it (esp. considering, those majority-to-most may be ev miles).
(Note, when driving from Florida to Texas last week, I noticed about a 1-2 mpg difference between night/morning driving and day. I am attributing those factors to heat, but I could be wrong. Anyway, I average 41mpg with a/c on eco mode, but I think I was getting up to 42-43 at night.)
Anyone has an opinion to do it? I am currently sticking to "not"....
