Geoshied IR70 - Thoughts?

Hi Everyone,

New poster here. I had a question about the properties of Geoshield IR70 (ceramic) in an automotive application. Wondering if 1) it's ok to use residential film on a car and 2) if installation difficulties are normal. (I know that some people don't like the Huper because it's so hard to work.)

I had my windshield done with the IR70 film, and the tint shop has had some difficulty getting the install to work correctly. On the initial install, they they ended up cutting two full-windshield sheets (tried once, threw away the film, tried again) and they still ended up with a crease.

On the redo, they brought in the owner to do the work and there were no creases, but after driving away I noticed a scratch (only visible when the sun/your head are at certain angles) and a small bubble directly in the driver line of sight (pretty noticeable once you see it - maybe 2-3mm in width). It has been about 2 weeks since the last tinting attempt.

Does this seem normal? I've tried to push down the bubble but it looks like it's there to stay. These guys seem like they want to do the right thing (they even threw in free red overlays on my taillights, and I know those things were a b**tch to install); but at the same time I can tell they're getting tired of me.

Thanks in advance for the help!

full windshield tint is !llegal in most states..some laws can be argued on the wording...with that being said...i would be grateful with the job you have..and move on.

its kinda like stealing something and then going back to where you stole it and complaining that it doesn't work.

Don't molest the water bubble....if it is water it will go away eventually.... As far as the scratch that You can "only see in certain light and with Your head tilted upside down"... If You have to go through all that to see the scratch, then it must not be that bad.

Thanks for the comments everyone. The windshield tint is pretty much clear (70% VLT) so don't worry about me running over kids in the parking lot.

I wouldn't care about the scratch so much but it does show up occasionally in daily driving (I noticed it on the road and it was distracting). Same with the bubble.

Does anyone have an answer about the suitability of flat-glass films for automobile applications? (windshield in particular)

Thanks!

Residential films can be tricky to install on vehicles because they are not designed to shrink like automotive films.

I have a sure way to fix your problem....

Get that Shat off your windshield and keep it legal !

Problem solved

i dont think that is the case.

Ok, then educate Me.

sure...how much you got...

Lots... really, I'm curious to know why its not the case?

Hi all - let me jump in if you don't mind (although everybody may already know this). It is not accurate enough to categorize 'architectural' and 'automotive' films as unable to be used in crossover applications. The historical paradigm I see in play here is that "you can't use auto film on flat glass because it will break glass" and "you cant use architectural film on cars because it won't shrink". Usually, both of these things are true (which is how they became paradigms) but you should check out the reasons why.

Automotive film typically has very thin metal (or no metal) whereas architectural film can have thicker layers of metal. It is the metal (and the residual stresses from the metallizing process) that makes shrinking difficult. Just compare shrinking of metal/dye hybrid auto films to pure dyed films. Regarding the film layer, it is true that not ALL film is based on the same PET ... only most of it.

On the other hand, automotive films usually aren't good architecturally because they are typically higher absorbing. This isn't a problem on cars because of the thick tempered glass. However, if you put a typical [dark] tint on thin annealed glass you can get a problem with breakage (not to mention it doesn't block much heat so why bother in an architectural application when you can get a film that also blocks heat).

Holla!!

There's a problem with this conversation... Geo IRIS 70 does not have any metal.

I think tintbuyer was trying to clarify why residential film can be difficult to shrink vs. automotive film, not necessarily talking about the IRIS 70

Complex stacked films and films made with components that are efficient at dissipating heat are challenging to heat form. Even when you can, it is the multi-stacked films that get so altered that the optics or performance is affected in a negative way. Both of these categories of films are made for auto and fg.

The way I understand it, it's !llegal in every state.

Aha - that must be why I'm seeing rainbow colored streaks through the windshield when I wear polarized sunglasses. The layers must have shrunk in a non-uniform way when they were fitting the the film to my windshield. Weird, but kinda cool actually.

Ok I guess I'll let these issues lie. The contamination I just found on my front passenger rollup is another issue however ;). It was hidden under the upper door frame...sneaky!

you'll get that rainbow with any tint. buy cheap sunglasses for driving your windshield is tinted.

vclimber-what company is geoshield reboxing from? i haven't received their stuff so i can't cross refrence. there are only certain manufactures that can stack films with good clarity.

Yes unless you have a restriction on your license. I do.

37% On my shield. Solarguard

South Korean company...

after you get your first ticket with that suspect film on your shield, you will need one less obvious like a UV75.

I'm sure the customers with the 20% front rollups and 2% tails would appreciate the same level of concern. Thanks for the

... level of concern!

Maddy Cool 35% to be exact and those tails are not cheapy overlays. All of the M5 lights were done in a spray booth at a high end paint shop. I will always be a fan of CP shield films.

give me an N.... give me a E.... give me an X.... lol

I think that maybe it is made by organic material to increase IR rejection.

I burn the film using lighter after taking off release liner, it's color turned yellow.

The organic, dyestuff change their color to yellow after burnning.

So,I think it's not stable to last long.

And it is really same with one of Korean Company.

hm..........

organic=unstable

Guess what happens after several years of exposure?
