So I am a rookie but when I started tinting I had a really experienced mentor (almost 30 years). I do not have him anymore as I regretably have moved on from his company.

Anyway, I have now twice tried to shrink and install back glass on friend's 88 Accord. Looked relatively easy, but not so much. I used the drier sheet method as I have used before, shrank most of the window with no issues. The edges of the window gave me serious hassle where the curve is the greatest. I expected that. However I was able to finally get it shrunk down after an hour of fighting with it.

The first install I cut my usual 1/8" past dot matrix. This did not work! It was too big. Plus I realized there was a ton of extra film like I hadnt shrunk enough. So I tried again. This time I was able to get a pretty dang good shrink job, and I cut at the very edge of the dot matrix..basically no margin of error. Oh yes and I also had to cut holes for the rear defroster terminals. The cuts looked perfect. The shrink was impressive to me as a rookie.

The problem was upon install, the film was still too big. the edges were past the dot matrix, and on this car there really is no room, past the dot matrix, just the factory seal or upholestry. plus the edges of the glass where most of the curve was still not appearing to be shrank enough.

Long story short, final install of back glass not to par and I will be going back a third.

My questions are:

Why was cutting right at the border of the dot matrix not working? Do I need to cut in further on these types of back glasses?

Is this a hard back glass for experienced installers?

Does a certain curvature of glass indicate that a piece of film needs to be considerably smaller to fit on the inside of the glass than it does to fit on the outside of the glass?

Tools used:

Wagner 2 stage heat gun (used on low heat primarily)

Turbo squeege

Bulldozer

Blue Max beveled

Used a flexible corner tool with towel for shrinking (gold ez-reach I believe)

Film: EWF/Concord HP Metallized charcoal 20%

Because of the sharp curve and the thickness of the glass the inside is smaller and the film needs more shrink. I hope that makes sense...

What he said. The thicker the glass the smaller the radii will be on the inside compared to the outside. You tend to find the older the car, the thicker the glass. I used to get similar problems with the Mk4 Golfs before films started shrinking that bit more. I used to cut them about 3mm shy of the edge of the dots, this would give me just about enough shrink to get them, when fitted they'd sit perfect.

Best I can suggest is pull some film from the top so you have some small fingers on the side, ones that you can heat a bit and lay down after the install. That will make for a little less shrinking on the top and bottom and less chance of creasing.

      Cracked glass

      Follow up: Attached is the performance data for Johnson's Resi/Comm window films and if you look to the bottom you'll see DN50 has a solar absorption of 39%, which is well below the threshold of concern which is generally accepted as 50% absorption (with no shadow). With a straight line shading from the roof this does increase the risk, which is usually low for straight line shading compared to other types. I've also attached a pdf of Johnson's film-to-glass chart which is used to determine how safe a film is. The thicker the glass the higher the risk; you say 6mm tempered and 4mm is the cracked one (interior pane). The question now is what compass direction do these panels face? In the end, I'll just suggest you hook back up with the person that installed it and get his input. He had to have been comfortable suggesting that film. I still believe it's a one off cracked panel and the rest will be fine. It takes 2 seasonal cycles to know for sure. Truly your call as to whether or not to replace with something lighter such as DN60. Here's more helpful info that helps you question the glass type on the interior; is it plate or is it heat-strengthened (HS). I believe it is plate and not tempered or HS. Why? Plate glass with suffer thermal shock if the edge temperature is different than the center of the glass by 50 degrees F. Heat strengthened requires 100 degree F difference, and Tempered requires 200 degree F difference. Ryker chimed in and that stimulated further review. Good Luck with this. johnsonFilmToGlass_2021.pdf

      Cracked glass

      Whatever that glass is that cracked it is NOT tempered. DN 50 is pretty high solar absorption and your saying shadows too so you probably need a more reflective film.

      1) Why avoid Suntek? I thought they resolved that issued with the easy scratching and that they are one of the market leaders in Australia? Also, it seems most of the well established Tint businesses use Suntek 2) I've heard mixed things about Rayno, with some installers raving about it and others disparaging it. Makes it difficult for the consumer to know the truth, given vested interests exist. 3) Is Ultragard a Australian exclusive product? The IP seems to be owned by GTS FILMS PTY LTD. How's the quality as it seems to have limited installers. 4) Is the MEP Films CNP that apparently are Manufactured by LLumar of the same quality as the LLumar tints (such as Llumar Formula One Stratos; Llumar Formula One Pinnacle; Llumar CTX)? 5)

      Cracked glass

      The crack indicates thermal stress, however, the edge of the glass may have an imperfection (bur or clam shell chip). The crack does run 90 degrees out from the edge and curves as it follows any weaknesses in the pane itself. I have attached a pictured of what tempered glass looks like when it breaks and alongside it what a plate (or float) and heat-strengthened glass looks like when it breaks. The outer panel my be tempered should indicate so by a stamp etched on the glass surface in one corner. It should indicate tempered. Plate glass has no indicators, however, heat-strengthened glass will crack in the same manner as plate glass. I'm an unsure whether heat-strengthened glass requires a stamp. Tempered glass is 4 times stronger than plate and heat-strengthened is 2 times stronger than plate. 1 in 24 is indicative of edge imperfection. I could not find the solar absorption rate of DN 50, but if it is similar to competitive films, there should be no issue with that installation setting (including a straight line shadow). This, too, points back to edge imperfection as the cause. And finally, I spy drapes in a close position, correct? If so, it would be helpful to crack open during sun exposure; this to assist in allowing trapped heat between the glass and drapes to dissipate.

      Cracked glass

      Hello. I recently installed Johnson Daylight Natural DN 50 on a couple of windows. Solar energy rejection is 39%. The windows are double pane and the glass is supposed to be tempered 4mm + tempered 6mm. The roof overhang shades the top 1/3 - 1/2 of the windows. However, a few days after installation I noticed that one of the glass has cracked, presumably due to thermal stress. Should I remove the film from the rest of the windows? I installed the film on 24 of these windows (6 tiny houses) so now 1 out of 24 is broken. Or is it more likely that I just got unlucky and the glass had a defect? Is shading from the roof overhang such a big factor? The glass cracked. Is it really tempered? I thought tempered glass would shatter, but not crack. Thanks!

      Residential Window Tint - Suntek SYDS vs. Solar Gard Slate vs. Madico Optivision

      Did you get this taken care of? What were the results and are you pleased?

      Residential Film without blue hue?

      Take a look at 3M's Nightvision or LLumar's Dual Reflective series, they both have a warm tone to them.

      Steer clear of Black Armour, Suntek, ASWF. The others are good choices if you are in Australia. Check out the reviews of the installer too. It’s not just the materials that have to be proper. Never go for the cheapest!!!

      Residential Film without blue hue?

      Hey guys I am in the process of having window film installed in my home but have a question about which brand I should go with. Hoping yall can help me out. I have a room that faces a busy street and as a result my blinds pretty much always stay closed. I love having natural daylight but not so much people being able to see what i'm doing in my room/all my expensive equipment. I used to work in the window film industry as a helper/installer/salesman when I was in highschool and we did a lot residential/commercial work. The specific brand of film we used always left a certain blue and cool appearance. Is there any brand of residential film that does not have this effect? I mainly just cannot stand having blue light amplified and am looking for a film that has a neutral shade to it or even a warm/yellow hue. I have single pane windows and I do not necessarily care about heat rejection but if I have to pay more for a ceramic film rather than a dual reflective or a standard film I am willing to if that helps solve the issue. Again, any help is really appreciated with this there are so many new window film brands out there and it really is cool to see how far the industry has come.
