I would not be happy with any of that tint. Tons of small contamination spots. The edge is likely dust nibs too.

I simply use global and don't worry about warranty. In 16 years I've yet to see a film failure with global. I had one from right before in some llumar though...

Lay the film on the glass, overlap top or bottom, mark the edges carefully with a marker, shrink whichever part halfway. Then lift the film off and move it a little to shrink the other part. Then you can trim the film to size or a little large. Should be good to go from there. Hit a little heat on the final install if needed.

The human eye isn't that precise.

I use global 40% to get in a net 35% here in Illinois. It will typically meter between 36% and 32%. That gets in the 5% allowed over for legal.... So yes, a true 40% film is the range you want. Now the fact is you won't likely see a difference if it is between 30 and 38% with your eyes. Meters are the only way... Some vehicles will look darker with a certain darkness than another similar vehicle. A darker car, darker interior, shorter, and or smaller windows... all factors. Overcast days the windows will look different and harder to see in due to the gray reflection from the sky.

They think they have some magic film, might be a film you don't carry like a more reflective, back in the day the fader films were popular and had a customer or two wanted to get me to do those, could be they think they are going to get a better price because they provide the tint. They don't understand that the film is a very small piece and it's more labor...

I won't put my name on anything but my own film. If you install something else and it fails then all people will see is that "xyz shop" did this job.

Or tell them it's double the price and if something happens they have to provide more film and pay for your extra time.

Tell them your price and tell them you only use your film.

You don't. You trust the shop or you don't. Do you question everything like this? Did I get an Angus steak? Was it US or Mexico? Was it really an 8 oz or was it 7.8 oz?

How long the shop has been around helps but the work they do is more telling. There are shops I know that have been "around" longer than I have but I was killing them in quality from the start. Here I am 24 years in. Go look at the work they do.

So you aren't measuring IR but a generic "solar heat". I've got the old analog btu meter and it was a cool tool but I don't use it and have not for probably 20 years. You are way overthinking this.

Unless you have a really high dollar meter you aren't measuring any thing worthwhile. It's also likely that the "96%" or whatever is a narrow band of IR.....

If it's qdp ceramic then I say go with global if the shops are equal if it's just qdp then you'll get better heat rejection from the llumar ctx....

Scroll up this post. Just above like 3 and he posted it.

Call Stan and see when he'll be in Saint Louis again. He's a great guy and teacher.

If that's a rear roll down window I bet the dealership uses key boxes.... they will rub about like that.

Having the ability doesn't necessarily mean that you are doing it.

I would love to know what they are paying you per sqft. If it's less than a dollar then I would definitely be looking for more. If it's more then I would be questioning how many sqft they are giving you. You should be able to do more than a couple hundred sqft per day easily.

Well I don't trust any film more than Global. Second in line is Llumar. "Lower end" I wouldn't really worry about the film. Pick one...

Try and put it in the sun and let it set until the window is hot then press it again.

I wouldn't use it but then again I only use film-on

If it's dry adhesive it won't work well. It will shrink just fine but not going to adhere well. I used sun-gard Nova on an 88 s10 blazer windshield over 20 years ago. It was detac ps adhesive then though.

So what of this list does Garware, Global, not make? You know Madico doesn't make poly?

I use llumar film-on and seldom do any cleaning of my bottles. I use RO filtered water and occasionally I'll rinse my bottles with some good old isopropyl 70%. I use Hudson tec hand held compression sprayers that I've had for many years.
