Similar observations have been reported on Solar-Gard Quantum and Sun-Tek Carbon. Same fact pattern, observable haze in direct sunlight only. Some very good pictures have been posted as well.

I am certain that it involves the base polyester. A small amount of haze yields a significant increase in solar performance. Hence, there is some "engineered-in" haze present in these films.

Some observers are more sensitive to it than others, as discussed in other posts. At the factory, they measure haze using lab instruments. Perhaps the threshold of what is acceptable needs to be reassessed.

This issue is a reminder of how shared raw material sources at the top of the food-chain can have a simultaneous impact on different brands of film. I know we all like to think of the brands we use as being "unique" but the fact of the matter is that most (or all) of these components are outsourced to a small list of vendors that supply the industry as a whole.

I do not understand why it would be present in NR-TB however, so it is imperative that I get the roll back. MWF: please call me today so I can arrange to pick that up. It is possible that one or possibly two layers of the "hazed-up" polyester made it's way into the film.

I will investigate it thoroughly and report what I find.

Difference in polyester quality ranges in a similar fashion to differences in final film product quality.

I believe higher quality polyesters, obviously costing more, will have the lowest amount of low angle haze issues. I could be way wrong here, but I've seen low angle haze in the cleanest of glass without tint applied so may times it could simply be the glare reduction of the film exacerbates the glass haze issue.

Could this issue not also include the Hard coat?

Edit: Never have heard that one, but who knows these days.

I have heard of this with films like 3M and there NEARL Films,the haze issue was due to the Hard Coat.as with other films made by other company's.

I guess we can add 3M to the list then.

It's not a matter of using cheap polyester to save money. A little haze bumps up the solar performance - that's why it's in there. Apparently, it's a bit too hazy in some films. It's a delicate balance between enhanced performance and optical distortion.

Making window film is not rocket science, but it is quite difficult to produce a consistent product when you are outsourcing 90% + of the product by weight. We would all like to have perfection from our vendors, but given the physical constraints and the pricing pressure, it's not going to happen.

A reputable supplier will always take back whatever you are not satisfied with. That is as close to perfection as we can expect.

      Stratos 70 on windshield, what is this?

      Captain Obvious has two cents err senses to share: 1) The film should be removed and replaced, because it appears to have adhesive blemishes that shouldn't be there, and 2) The film should be reviewed/inspected once taken from the roll to avoid losing time and resources due to manufacturing issues. Little pieces not so much, but back glass and windscreen pieces ... definitely.

      Olfa blades are not as sharp as they used to be

      I switched so long ago... first to KDS but they went away. NT are great though. I use a piece of white strapping material as a cutting buffer between the blade and glass. Some use a button but I didn't like the feel..

      Headlight Taillight Vinyl question... (Looking for CHROME)

      I'm looking for a chrome/mirror wrap for headlights/taillights. No NEOchrome, just a mirror or chrome appearance. Looking to spice up a project. Looking for transparent so can see lights thru film. I have looked and can't find what fits the bill. Any help appreciated. Thanks in advance.

      Stratos 70 on windshield, what is this?

      I can't win with getting tint decent on the windshield. I had 3M on my F150 done twice and still has major defects. Recently did Stratos twice on my F350 and I see this granular spotted, texture pattern on the tint. It's super obvious in the corner here but also right in my view when driving. It's honestly hard to point out and show someone but when your driving and stuff is moving behind the windshield, it becomes more obvious. The lighting also matters. The first time I did the windshield, I had a two foot line on the windshield. Thinking it was tint, they removed the tint and it was apparently a defect in the Ford windshield. An issue between the laminated glass layers caused this big defect. So they removed the tint, I had Ford replace the windshield on a 2024 F350 but when the tint shop removed the tint, they made a bunch of micro scratches in the front windshield, probably from scrapping the glue off. I told them but I didn't care since Ford was replacing the windshield anyways. So if basically I'm trying to figure out what this texture stuff is and if I should have them replace or remove it. Replacing it might just have different issues but also afraid they will scratch the windshield.

      Wtb Solar Gard Supreme NR 40

      I would direct you to Express Window Films web site. They sell Global brand after setting up an account with them. They are reasonably priced and they do partials. Can't go wrong with Global.

      Need some help

      Never overlook the condition of the floor. Back when I did install, I used to mist the floor between the vehicle and the peel board. This is done between misting the window and walking toward the peel board to mist the pattern liner, peel liner and spray adhesive for install. Tacks any dust for the duration of each pattern install, so repeat each time a pattern is going to be installed.
