I was thinking about Limo Tinting (85%) all the rear windows in The Park Ave.
With a black limo tint though do you think it would cut the interior heat down from sun entering or make it worse being blacked out?
My last car had the tint done and when sun hit it darn it got hot back there, and once it was done, backing up you had to be careful at night.
Is there any other ideas or color to keep a good darker interior cool?
Silver? LT.Blue?

Just a gut feel on my part, but I would think silver would keep it the coolest since it reflects the heat instead of absorbing it.

I think ur right Roy. Might look kinda bad though in silver....cheezy...?
Oh Gosh...wish the PA came with Factory blacked out like the Jeep did. It stays 20 degrees cooler inside than the PA.

get tint that blocks the uv rays. my girlfriends triple black civic would get about 800 degrees in the sun. to the point you couldn't shift or touch the wheel. i got some tint that blocks 100% of the uv rays, and now its only slightly warmer than outside. its great.

What Tater said.

Tint doesn't work by it'* color, it works by blocking UV rays. So 5% (black/limo tint) will do the same as 70% tint if they both block UV rays.

You also have your numbers mixed up. The lower the number the tint, the darker it is. Tint is rated in how much light it allows through. So 5% tint allows 5% of light in.

The best way to tint your car is this: TINT EVERY PIECE OF GLASS ON THE CAR!

I have 15% on all windows on my Bonneville, except the windshield. The windshield has 70% tint on it so it doesn't hurt my visibility, but because it blocks UV the cars interior stays cool.

Jason & Nick Thanks a lot, good info, that gets it clarified!
I can only do the rears as it is illegal to do the fronts apparently.
I will call a trim shop and ensure that quotes are for best 100% UV dark tint I can get.
I remember after time, that last tinted car faded and eventually it was no where near as dark form years of sunlight.

You CAN do the fronts, just do them a really light tint, like 70%. This way they'll look untinted, but you'll get the UV blocking benefit.

Yes, to further flog a dead horse, make sure your tints are uv proof. The heat is coming from the unseen uv radiation emitted by the sun, not necessarily the sun light you see...
You can theoretically get really dark tints without any protection and it will just absorb all the visible light and make things very hot, or you can get very light tints with uv protection and it will block a lot of radiation that you can't see and make the car significantly cooler.

So in conclusion, get dark tints for the back, and light tints for the front, like previously mentioned, but make sure its uv protected. If not, you can get the darkest tint, sweat a lake, and end up looking like this guy:
