Many of y'all here may not realize it but there is a lot that goes in to the making of these videos. I was there when portions of this was made to kind of give feedback and support and I got to give Ralphy boy some serious respect! This was an especially difficult video due to the content.

Good job buddy!

No . I actually use a different brand . Me and Ralph are good friends though. He lives about. 30 minutes from me .

He means well and has really taught a lot of tinters a lot of things. We bounce ideas off of each other a lot . We just have mutual respect for each other . Funny thing is when I first heard of him I had a bad view of him . But when I met him I realized I hadn't gave him much credit .

Again I'm not here to promote any film , not even my own. If anything I'm just here to learn, socialize and generally just have a good time . I could honestly care less who uses what film . If I'm asked about any specific film , well I have an opinion just like anyone else.

I read this forum a lot but have never posted before - but I wanted to share some thoughts on this video.

 

I like the intent of the video - it simplifies things and is mostly accurate. However, TSER does take into account absorbtion - it uses a steady-state calculation to break up absorbed energy into what is re-directed (either by radiation or convection) inwards and outwards.

 

There is some validity to TSER being less applicable to a moving car because more of the absorbed energy is pulled outwards due to the relative wind speed. But to say that TSER only accounts for reflection is unfair and would put in in the same category of "IR Rejection" - which does only account for transmission.

 

Lastly, the IR lamp is a great tangible demo - but it definitely has some inaccuracies as well. Solar energy is almost 50/50 split between visible and IR but the heat lamp is mostly IR so it gives an uneven weighting to IR rejecting films.

I agree with you.

I have however tested the whole heat lamp vs normal full light flood lamp side by side and could only feel a very negligible difference if any at all.

You also must keep in mind that the visible light isn't necessarily causing any discomfort to the vehicle occupant.

At least not heat. ( yes I realize that light accounts for energy but energy and heat aren't exactly the same.)

IR in specific is the part of the solar spectrum that your body actually registers most easily as heat.

Imo if you reduce the ir you increase the comfort.

      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.

      Olfa blades are not as sharp as they used to be

      Yeah, at least a decade ago rumored to be different as a result of a US based manufacturer making Olfa blades sold here at home. Of course, Olfa would deny coupling up with a US maker. I, too, switched to NT.

      Olfa blades are not as sharp as they used to be

      We have been using olfa blades forever but in the past year we have noticed the quality of the blades is not the same as it used to be. Blades are not as sharp and pressing harder is starting to etch the glass on certain vehicles. Would like to know if anyone else is experiencing this or is there a better brand ss blades that you have been using that is a better trusted brand.

      Bump on this. I spoke with Film & Vinyl Design and the rep told me their cutting software contains the drivers for the Graphtec 4100 models. They also mentioned it will work with Windows 11. Any one have experience with this program, good or bad things to say about it?

      Need some help

      Push out all the air you can then… Heat up area with heat gun and use a hard card to press them down while everything is still fresh… don’t over heat prep work is key… you can also use masking tape on the gaskets and carefully peel the tape out once you have all the fingers out
