Your Questions About Car Window Film Reviews
Daniel asks…
Recommendations for car shades?
I’m a wit’s end with this whole car shade thing! I have a 4 month old daughter and we live in Florida. Needless to say, keeping her shaded while in the car is essential. I have tried several different types of shades and they’re all cr*p. Seriously, who thinks making a tiny square shade that doesn’t even cover the whole window (or that extra little triangle-like part of the window that the sun ALWAYS seems to peak through) will be the least bit effective? The ones I have now have cute little animals on them, but they have to hang off the windows; you can still hear a whistle from the wind since they clearly hinder the windows from being completely rolled up. In Florida, it can go from sunny to rain and back to sun again in a matter of 20 minutes so I have to try to anticipate when rain is coming, pull over and take them off so it doesn’t come through the window on my little girl and then pull over again to put them back on so she’s not blinded by the returning sun. They’re not very effective shades in the first place so I’m not sure why I even bother with them sometimes. I managed to find a halfway decent rear shade, but I had trouble seeing through it at night and it was such a hassle to take it off and on. Plus, it ripped because I overpaid by $19 (it was $20) and is also rendered useless. I’m at a loss. I’m considering ordering some tinted film off Amazon and cut it to the shape of the windows; however, all the reviews I read for all the different kinds either say they’re not dark enough to produce proper shade or they’re too dark and cannot be seen through at night. I don’t want to splurge on real tinted windows as we plan on getting a new SUV in about a year so we won’t have to worry about this silly shade issue since they’re all tinted.
Sorry for my little rant.
Any success stories with car shades or should I just suck it up and get the darker tinted film?

I like the static cling car shades. And the ones built into the car seat, the hoods. With my last car, I put a blue tint cling all along the back window, and the side back windows. My sister drives it now and she took them all down, but I found that I could see out the back window well enough because it was blue, and it blocked the window, and kept the car a good 10 degrees cooler in the summer (no AC.)
So there’s this link. I tried it, didn’t work that well, just stayed blue all the time, but that did work to do the side windows. I bought another (they were on sale) and cut and fit them to the side little triangles. The blue was what I ended up looking for in clings because it seemed to work well.
Second link, if she’ll leave it alone, a hood works really well but my son hated that it impeded his vision.
Third link, sort of what I found. Mine was just a huge roll of window cling that was blue. I never noticed that it impeded my vision, because it was blue it was easier to see through, but it sure cut the UV and cooled the car.
Keep in mind that tinting in some places are against the law. Course, with the static ones that I used I could pull it off if a cop said “that’s too dark” or something. But it really helped with the car we drove.
Another idea is to just put washrags up in the windows. That’s what my parents did, they would roll the window up with a washrag hanging from it and let that block the sun from us. Doesn’t work for the back though.
Donna asks…
How do I find the temperature at the surface of glass with film in middle?
Got a test in thermo tomorrow and I am not real sure about this question. Logically, this question just does not make sense. The question is asking for the temperature at the surface of both sides of a window . The system the problem describes reminds me of a car with rear defrosters. There is a thin sheet of film sandwiched between two sheets of glass with x thickness. The k for glass is 0.7 W/m*K. One sheet of glass is surrounded by an environment at 25C and the other side is in 0C. I know the heat transfer to surroundings is through convection. The h value for the 25C side is 20W/((m^2)*K) and at the 0C the h=80W/((m^2)*K). The review question asks for the temperature of each of the two surfaces. How do I find that? Also, I think it is important that the film is between the two sheets of glass, but does it really affect anything in this problem?
Sorry. Forgot to mention. The film (or heater) is OFF. There are no constants given for the film . I may need to know how to represent the film in a drawing though.
mariok answers:
Do you have value of X?
Assumptions:
A =cte , not heat generation, steady state condition
If valuable of X has been given:
Rtot= 1/h1A + x/KA + 1/h2A
Q=(Te1-Te2)/Rtot ——–> T1=Te1- Q/h1A Te1>Te2
if x is unknown:
Q=(Te1-T1)/(1/h1A) = (T1-T2)/(x/KA) =(Te1-T2)/( 1/h1A + x/KA )=(T2-Te2)/(1/h2A)
You can write 3 equations with 3 unknown of T1,T2 and X.
And solve it.

Mandy asks…
Review my poem, please? I love you?
I REALLY need an actual answer, please!
The Homeless Man
I see him stand streetlight rays.
He shivers from the dark.
Every night he shakes hands
With the incoming night.
The grinning moon brings him his
Nightmares.
The grinning moon offers him cold-served
Fear.
A pepper and salt beard sprout from his creased face,
Smudged with gritty life
And blurred by smelly fate.
Moonlight eyes peek from his denim hood.
Although they are so careless,
They scold me for my luck
And beg me to change his.
His hands are florescent skeletons
And his body a pile of wrinkly firewood.
He’s just crumpled against the gray, skyscraper world,
Life playing like film in his bright eyes.
Sometimes he laughs,
His hallowed-cheek face thrown into the sky.
His head rolls around on his shoulders.
He points and barks and grins so wide,
But there’s nothing to laugh at.
He laughs hard enough to summon fat, round tears.
He dances like a merry man in a crowded, gold tavern.
All I see is a man grinning,
But at a different world.
And sometimes he cries,
He shouts and runs and fights so hard,
Against demons who you can only see with special glasses.
He begs for his own life,
Which he can’t even see.
But he doesn’t see the eyes flit
From behind car windows rolling by.
Those gray faces don’t shed a drop of anything,
They just roll on by.
And he laughs.

David asks…
am i the only one to think that the movie 28 days later isn’t very good?
for many years i’ve wanted to watch 28 days later but never got round to seeing it until today. i had an idea of what the movie was about; a sort of day of the triffids/night of the living dead plot. i was expecting a lot from this movie because of the positive reviews.
however now that i’ve watched i feel kind of disappointed as it didn’t really live up to expectations. i just found it unbelievable – the way the different characters behaved with each other. the storyline and characters were not really developed or were not believable, some examples are:
The character of Frank – why does he have all that military kit in his flat when he’s a London cabbie? Also it seems weird that him and his daughter are the only survivors from his block of flats and the whole of London.
The actress who played Hannah is really bad I thought… her accent was odd and acting was wooden. When she says to the military leader ‘that’s my dad you’re talking about’ i think it’s meant to pull on the heart-strings, but just doesn’t do that and instead sounds really cliched and fake.
When Frank decided to recklessly drive through the tunnel (hmm when they know that the infected thrive in the darkness and there are dead bodies near the entrance). Jim even says ‘don’t go through here there’s glass and stuff everywhere!’ – why would Frank be so mindless, endangering his daughter’s life by driving through like a lunatic when there’s another, safer route he could have taken? The same Frank who only allows his daughter to take half a pill of valium and tells her to ‘stay in the car‘ later on in the film?
When they manage to change the flat tyre and start driving off just in time before the infected catch them… why does Jim stick his whole torso out of the window and jeer at the infected ‘cunts’? Again, this seems like a unoriginal thing to see in a film and similar rebellious gestures were probably unconciously copied from films like Trainspotting etc.
The way Jim’s parents overdosed in bed like that and that message they left him on the back of the photo saying ‘don’t wake up , x ( kiss)’ sounded so cliched. Also Jim’s lack of emotion at finding his parents dead is unrealistic.
How Jim manages to foil the army’s plans with no weapon, his hands tied together and shirtless? and how come he doesn’t get infected during his time outside?
The soldiers at the military base… so completely unbelievable. At first they come across as an organised force but very quickly descend to behaving like a bunch of rapist monkeys. When Hannah says ‘I think they’re all dead’ and that young-ish soldier looks terrified (really bad acting) and he says to Hannah ‘shut up, i said shuutt uupp!’ – i mean surely as a trained soldier and somebody who’s witnessed and survived this ordeal himself, he would be able to keep his composure when a little girl is saying stuff.
the whole thing about needing the women to pro-create is so damn stupid… what kind of sick people would do that?? and even if they wanted to have children with the women or whatever… they could have waited a little longer until the immediate threat of the infected had passed and let the women themselves decide. also i doubt a major would accept this… he was older than the soldiers and probably had a wife and family who died, no-one in their right mind would then allow for a women and young girl to be effectively raped.
If you think… all these cocky stupid soldiers (I spotted that guy off Eastenders and another off Grange Hill), well they’re all meant to have lost their whole families; parents, siblings, wives, girlfriends etc. In real life I don’t think they would have acted as such asses the major would never have let it descend into chaos like it did.
Lastly, this may seem like a basic point, but the infected did not seem to be that strong and surely could have been halted or contained more effectively and non-infected people could have been moved to many fortified buildings, where the ultimately flesh and blood infected people could not enter. Note that whenever the infected do enter a building in the film , they always seem to suddenly jump through a window (like in Jim’s parent’s house) or just run towards them in the street. They wouldn’t be able to penetrate tightly secured premises and buildings, no way.
This movie is filled with holes… very overrated in my opinion. I actually really wanted it to be a realistic and believable story but it just wasn’t. and this had more to do with the non-infected people’s behaviour than the actual infected.
