Are you guys sure the factory rear windows are 20%? Mine don't look anywhere near that dark :nono:
I believe they are 30%

Original poster here. So i went with 20% all around, but my decision was easier in that the pro tint shop i used had 20% as the lowest tint for 3M Crystalline, which is what i went with. They had 4 "brands/levels" with Crystalline being the 2nd to the most expensive. I picked it for heat rejection, and even did the windshield with 70%, although learned immediately that heat rejection is a load of marketing crap. Might make a separate post on this entirely.
Anyway, 20% over factory is NOT too dark on the rears, I can see fine at night. I would have even gone darker, so 18% is indeed a sweet spot, and I can even see 10% doable! 20% in the FRONT is perfect, albeit illegal where i am. But tint decisions are not just willy nilly, there is a safety aspect....you don't want to be driving in your suburban neighborhood and not be able to see around you. I also took the guy's advice as he has been tinting for 30 years: if you go too dark in the back (limo) it feels you are driving around in a closet. All that said, I guess I can't complain.
Last point is it was definitely not cheap. I took it to the best reviewed Tint shop in Phoenix and indeed they were great but it came to $1050 (3M Crystalline) for those pricing out. (4/19) including front windshield.
please either post here or separately regarding the marketing crap of the heat rejection... im about to get my windows tinted and would love to hear your thoughts on the topic
Sure man.
Save your money. I am going to call this "The big Tint lie"
This has to do with science I am very curious about. I get it. I do. But here is the marketing: "Light tint rejects 60% of solar energy and up to 97% of heat-producing infrared rays for the ultimate in comfort." "Reject heat" cooler car, etc.
In the installer, they have an infrared light behind the various tints. You press the button and feel the heat (or lack of) behind the tint. 100% convincing. This is REAL - your hand does not lie.
But in function, and in the science behind how heat actually builds up in a vehicle, it is 100% BS.
After tint, my truck is seemingly not 1 degree cooler than prior to tint. I am not one to fall for placebo affect easily. So I did a search and found some guy ran an actual experiment which proved my suspicions in a Tesla.
Experiment: 3M Crystalline Tint Makes ZERO Difference in Cabin Temp | Tesla
So basically I just spent just over $1K to have darker windows which I could have done for $350. I was expecting a significant different in temperatures. THAT WAS THE WHOLE POINT of paying premium.
If anyone can find another real world dispute of this (or explain) I'd love to see it. And before you say TIME may be a factor, I am talking literally minutes here in Phoenix before its intolerable, same as before - and it was only 82-85 yesterday. AND keep in mind compared to many vehicles our windshield angle to the sun is much LESS horizontal than most.
I'd love to see the industry have real world measurements in addition to all current stats: A chart of Degrees raised over time (e.g. 30 minutes) on a standard industry platform. But that might mean we see this "alleged" BS, so don't expect that. But I am just 1 guy.
Thanks for your input. I read the link you posted and while the initial experiment was decently thought out, there were a couple things missing.
One- the windshield was not tinted which as we all know, permits the most amount of light and heat into the car (depending on angle of the sun).
Two- the model 3 already has IR rejection built into their side windows so tinting those windows wouldn't really help too much with that specific car.
Three- there is a problem with the assumption of the experiment to begin with: that tinted car should be cooler after x # of time. While that assumption might be true for a short period of time, it isnt going to be true for an indefinite period of time. For example, you bring out both cars (tinted and untinted) and let them sit in the sun for 5 or 10 minutes. The tinted car should in fact be a bit cooler inside than the untinted one (assumed no IR rejection built in the glass already). However, if you let both cars sit in the sun all day, eventually both cars will be the same temperature inside. The takeaway is that perhaps the untinted car will take lets say an 60 minutes to get to maximum cabin temperature, the tinted car might take 75 minutes to get max temp.
so all in all, i don't think you actually wasted your money. what do you guys think?
I used 3M Crystalline 50 mainly for UV and heat rejection so my arms and face don’t get burned.
Sure man.

I absolutely love the 3M Crystalline stuff... I am getting the clear 90 put on the windshield. Cant even tell its on there.
Its amazing how well that stuff works from a UV and heat rejection standpoint.
Expensive, but its about best best stuff i've ever used.
A vehicle does not only heat up through its windows. Your roof is receiving direct sunlight and there isnt much in the sense of insulation from the roof and the headliner. If you have a darker vehicle, itll be warmer than the same vehicle in white. Tint and window shades help with surface temperatures that can radiate heat making it seem hotter in the car. Ambient temps will rise no matter what. Its a sealed box.
I view tint as a privacy thing rather than a heat repellant. Thats why I only spent $175 on 20% fronts and 35% in the back windows. They'll probably fade in 5-10 years and turn purple, but strip and spend another $175 isnt that much a of a deal to me.
To be honest, if I had to do it over again on my T4R, I would go with the Llumar CTX ceramic instead of 3M Crystalline.
On paper the 3M Crystalline is better than the Llumar CTX.
In the real world, my Tacoma has Llumar CTX and I can't tell the difference between it and the 3M Crystalline on the T4R in terms of feeling the heat. And the Llumar was half the price of the 3M.
That a good tip, perhaps ill look into that and save myself a few bucks.
I felt my tint shop who is 3M certified has pretty decent pricing on their film… about $200 for a windshield. Do you know how that might compare to what you are paying?
