Window perf lifting in corners... solutions?

edge seal strips are just clear laminate cut down to rolls, nothing fancy. vinyl strips will work too, you're just capping the "fingers" of trimmed perforated vinyl that will be the first things to start peeling-away over time.
I have some rolls of clear gloss and matte edge tape. Just wondering if black vinyl strips might look nicer. Someone mentioned elsewhere in the thread that the clear strips sometimes stand out and don't look good.

Somewhere on the forum someone posted that they had wrapped windows in black vinyl and one or more of them cracked/shattered from getting too hot. I know that's not what's happening here, but if this ends up being a redo should I suggest to the customer to not go with solid black again, in addition to using a cast vinyl?
I wrapped a bunch of windows for a Toyota dealership in TX with 100% black vinyl. Two years since and no cracked windows. That is a myth. I've applied graphics to tinted windows before and they get HOT. Glass cracks when there is a big change in temp in a short period of time. My brother in law that helps me with installs works at a glass manufacturing company. He regulated the temperature of the furnace.. it's 1000 degrees in there and glass doesn't crack.

Two years since and no cracked windows.
In the interest of dragging the debate up and around again, I think it tends to happen when folks aggressively apply the vinyl well over the rubber gasket. If it stays, then as the window and frame expand and contract away from one another, the vinyl compromises the rubber in a way that keeps the glass from 'slipping' in the gasket. So not like the vinyl and temp differences are the problem, it's the vinyl causing the glass to bind and self destruct.
But I really have no clue, I've covered windows before, nobody's come after me for glass repairs, though I stay off the rubber just for the sake of keeping the edges from collecting dirt.

Encouraging news. I know this was a recent topic on the forum, and not a week later I got a window job in with full coverage, lots of black. It's a redo of some failing vinyl and I'm going to use perf this time, trimming 1/4" from the gaskets to edge seal. The old stuff has been up there for 4 years and no glass cracking, so I decided to go for it.

The job is done, I used laminated perf with clear edge seal all around.

Took me 7-8 hours to do all the windows and I felt like I had been in a knockdown fight afterwards. Those on-the-ground small windows are a killer! Crouched down trying to trim straight lines...not easy. It was like a paid yoga session.

Yea I trim to 1/8" from the silicone. I use a straight edge and just go along the sides just inside the edges for that reason. I'll trim a little and use edge tape and see how that holds
How did this end up after all? We're getting complaints from a client self-install about peeling and I'm wondering about the solution. We print and inventory these to send out to locations on demand for self-install. These couple decals are local, so do we just supply them with new ones, or will edge seal tape fix this? I am now aware of 3M 8514 edge seal tape, but these seem a little far gone. We may include an instruction sheet "Do not touch within an inch of the adhesive edge. Use included strips of edge tape to seal all 4 sides." Any other advice?

That seems irregular. Specify to applicator to use 70% alohol to the area where they are applying. Other cleaning products will leave residue, that will hinder the adhesive from attaching properly.

Are they laminated? It is odd that it appears most of the issue is at the top and bottom and not on the sides.

I wouldn't recommend putting perf on anything other than glass....it appears the metal surface has some texture to it. Seeing that you have anywhere from 30-40% of the graphic with no adhesive, that is asking a lot for a good adhesive bond.

Thanks. These are not laminated, and weren't intended for install on a metal door (the dreaded self-install wildcard!) We may pivot back to rigid board, mounted inside the window. I'm still looking for a window perf that I can print and mount inside the glass.

There is clear perf if you have white ink. You print color-white-black and install 2nd surface.

Since the graphics appear to be so small, is perf really needed? If it isn't really needed, then switch to Polar Smooth 150 Air which is 6mils thick with a clear removable or permanent adhesive and an air-egress release liner. A drunk monkey can put it up without wrinkles or bubbles. The adhesive is clear so it looks good from the inside, too. Rolls are around $400 so probably about the same as what you pay for the perf. Lastly - the film can be applied in crazy cold conditions and will perform for 7 years unlike the perf. If you send me your address and a UPS number, I can send you a test roll to play around with. My email is Mark@HascoGraphics.com

A lot of time failure is for lack of prepping, even if it doesn't looks like some of the glass got a oil on them if is not cleaned the vinyl won't adhere the way is supposed to, also window perf needs to be laminated for outdoor use for a longer lifespan of the print, if you don't want the corners or any edge to start lifting you can always use 3M primer only on the edges, we usually do it with a Q-tip just so it seals the edge from moisture I have done this for years on vehicles with excellent results.
