Did I just get screwed with more expensive heat resistant tint?

[fuzzybabybunny]

So I decided to pay a premium for Llumar AIR film in my fronts - it's 80% clear film with the ability to block 40% of solar energy. They had the film under a heat lamp and it blocked the heat really well.

I'm sitting here in the car and I'm realizing something... all that demonstration showed was that it could block convection heat. If I had a heat source outside my window it would block the heat. If my car were in an oven it would be great. But sunlight isn't convection heat and is still shining on my black interior and making it warm... so did I get screwed?

 

[coxmaster]

Depends how much you paid.

Plus, 80% tint? Really? My car came with darker than that

 

[Throckmorton]

The sun does emit infrared radiation, so it's going to help just like if it were a heat lamp. With the little experiment, did they compare it to regular tint??

80% tint though is nothing, I put 5% on the inside of my prescription swim goggles, and I'm surprised how light it is.

But sunlight isn't radiant heat

Yes it fucking is.

the goggles, they do nothing?

 

[MJinZ]

80% .... wow. You are blocking 20% of the sun, that's like nothing.

 

[NutBucket]

Why even bother with 80%? I would have gone for 35% at most if I was going to bother at all.

 

[EightySix Four]

80% .... wow. You are blocking 20% of the sun, that's like nothing.

80% of the visible sunlight /= 80% of the energy from the sun. It's obvious he was doing it for the temperature difference, not the looks.

 

[ViviTheMage]

20% on windows, 15% on rear ... c'mon now. Tint really reduces the glare of the sun on snow, I love it.

 

[T2urtle]

any tint will keep heat out but it will also keep that ever heat in as well. I normally just run 3m tint or something close to it. I do it mainly for looks, the shade is a 2nd and i guess keeping my radio out of plain site.

You didn't get screwed if you paid sub $150 for tints on your fit.

 

[alpineranger]

Most of the heating in a car on a sunny day is due to radiant heat. Your tint only blocks 40% of that, and the sun is a lot more powerful than a heat lamp.

 

[desy]

you certainly can tell the diff on your arm against a tinted v non-tinted windows for heat

 

[thescreensavers]

80% wtf, waste of money..... I can put Blue Teflon wrap in front of a heat lamp and it will reduce the heat...

I bet you dont want to tell people how much you paid.

 

[fuzzybabybunny]

I corrected to OP to say the tint blocks convection heat transfer from the heat lamp in the example, but sun is radiant heat. When sunlight hits a dark surface on the interior, it's still going to heat it up as if I didn't have the film over it, no?

I did 80% because it's illegal to tint the fronts in Cali. Doing even 50% would be chancing getting a ticket.

 

[NutBucket]

Eh. Unless you're drawing attention to yourself the chances of you getting a ticket are slim to none. My last car had tinted fronts...definitely more than 80%, plus it was lowered, aftermarket wheels, etc and never had a problem. My fiancee's car is lowered, dark tinted, wheels, loud exhaust and all and never had an issue. Its all about the driver, not the car. People are hassled for a reason.

Just my $0.02.

convection heat transfer: movement of hotter medium to be replaced by the cooler medium due to differences in relative density.

Radiant heating is just heating caused by direct sunlight.

I'd have thought that tinting doesn't block convection heating by itself. It would reduce radiant heating which then would reduce convectional heating. So i'm really wondering what you on about when you say it blocks convection heat transfer, especially from a heat lamp...

I'm just saying that I wasn't thinking correctly. They had a setup at the shop where they had the different tints mounted in front of a heat lamp, and you could put your hand in front of it to feel the drop in heat as a result of the film. They put the 80% film in front of the heat lamp, I felt a steep drop in heat, and I went "wow!"

Now I think I got duped because all it was blocking was convection heating, and most of the heat buildup in a car is due to radiant... which 80% isn't going to block much of...

Are you both mexicans?

 

[NutBucket]

Are you both mexicans?

How about no.

 

[T2urtle]

in the end its how much you pay... since i guess your not posting...i think you did then. Cali is a big state and i've found out everything automotive wise is cheap in cali as compared to other places.

i rolled around in 35% tint when chicago had no front tint laws. blk/blk car, lowered and only got issues 1 ticket in 4 years.

 

[angry hampster]

Try wearing polarized shades.

 

[alfa147x]

Are you both mexicans?

Hahaha! I was thinking along the same lines

 

[Saga]

How about no.

I was just being curious. In just about any place I've ever lived, the only people that lowered anything were usually Mexicans. Considering it's an absolutely retarded modification and all, I just sort of assumed you were Mexican. I'm sure others would agree with my stereotype so don't get too angry. Most sane people don't see any point in lowering shit.

Lots of car owners lower their vehicles. I'd say 50% of enthusiast owned corvette's are lowered (because it's easy to do from the factory) and many after market performance suspensions are naturally lower than the OEM version.
