how'd you gonna shrink films with high IR rejection???? :lol

I'm inclined to believe that high IR rejection is for the near infrared delivered by the sun and not so much with far infrared produced by the heat gun... if the film were good at rejecting far infrared, then you'd also have low emissivity (low E) capabilities with high IR rejection, too. :lol

Heat gun should work fine provided the poly has shrinkability. Sometimes though, the new tech films require stacks or layers of particles (whether ceramic or metal), which translates into multiple passes through the machines. This stacking can create shrink challenges.

IR films fact or fallacy...:DD

IR only covers 53% of the solar spectrum so those numbers may sound reeeaally good, but let us not overlook the role visible light plays in the heat (gain) equation. :DD

Has anyone in tintland seen or heard about using infra-red from the big manufactures to shrink there films as to using heat guns?

Yes... I have heard of this. The result was not what you would expect, but the electric blanket theory may do about the same. :lol

Need a heat gun at this stage... no other method ::er:: wait... I heard that there's a shop in Cali or Oregon that uses some kind of a bazooka shape hot air gun (used in roofing) to heat form. Word has it... daaaaaammm that shrinks fast!

Never have followed up on it... too bazaar and a good one will run in the area of $500 or more.

:booga

      I am looking for an experienced Window Tint and/or PPF installer for a new shop opening in North Dallas (Frisco, Prosper, McKinney area). Must be damn good with a strong work ethic and put out quality work. You’ll have plenty of freedom but work is expected to get done as customers come first. For the right person, Job has the potential to become more but that depends on you and your goals. Feel free to reach out anytime.

      TintX Puremax and Koolmax

      All Right cool. I've been practicing with an inexpensive tint I found on amazon. Its called Rockrose. I'm just about ready to make some cards to pass around to get clientele. I've been debating if I should start with Puremax cuz its a lot cheaper or Geoshield cuz of the great quality I've heard of. I'll probably go with Geoshield so I can make it easy on myself and make sure I do great quality work for my customers. Are you already doing doing jobs for customers? If so, did you stop using the Puremax and now only use Geoshield?

      Heavy Ghosting - Geoshield "Geo" Line

      Ghosting week require a smoother, more even and spread out shrink. Look at my old "ryk shrink" using 2 heart guns with an over/under setup. That would be my suggestion.

      Heavy Ghosting - Geoshield "Geo" Line

      Hey all, I am not a pro tinter but more or less just someone who likes to experiment / DIY. Wanted to ask if there was anyone here who has used the Geoshield "Geo" line for automotive purposes? I really like the color, but I get really bad ghosting for anything that requires decent shrinking. The film is specced as architectural, but has a PS adhesive so some use it in auto applications. I sent an email to see if that is the reason why it's for flat glass .. lol This is a sputtered TiN film and has a beautiful color imho. This reminds me of Huper Optik, and not quite sure but I think Johnson had a line called "InsulatIR" that I could never get my hands on to try. The film has a slightly purplish reflection (TiN I guess), when put on green auto glass, filters out and looks super neutral. ❤️ I've had it on my auto for a while but my rear window is a mess when the sun hits it (ghosting) and was curious if this is just not suitable for auto Any info would be appreciated. Skill issue, ie: shrink with lower heat? lol Thanks.

      chameleon window tint good quality

      If you don't mind trying to source some, there is a large Japanese manufacturer that makes a bunch of dichroic - looking films. It might be your style, but it would be hard to get your hands on some. https://www.braintec.co.jp/filmlab/ I believe some of the films do have decent heat-rejection, but because of the nature of the films, looking through them can be really funky. They are well-known in Japan and would likely be of decent quality. Also, very expensive. Depending on where you are, shipping would also be $$$.

      TintX Puremax and Koolmax

      I feel the difference in quality with geoshield. Not only is it easier to peel the liner off but shrinking feels better and I think the material feels slightly thicker(helps with not creasing) Only downside that the price noticeably different. For mainly everything Its atleast another 100 on top of for example stuff from tints Lexen. I haven’t tried solarfree either.

      Automotive Tint Comparison

      At least twice, yes. Although since we don't know what vehicle it is you're planning to tint, that was a bit presumptuous of me.
