sign writing on car rear window

[Steve Sandy]

Hi Eltel,

Inside should be the best bet, You have said the wiper blade could catch being one, Also you wont get anyone picking it off either. Kids or other competition can be terrible things when bored. I have done quite a few comedy stickers and tribal designs on windows for people and I always go on the inside. Its nice and warm inside as well. Oh if you can heat the window a little beforehand to help the vinyl stick better.
Regards
Steve 😀

Steve is right, but I always put it on the outside.

A sign inside will not be as obvious to someone looking at the glass from an angle, because the glass will have a reflection, which will reduce the effectiveness of the sign.

The outside, the reflection will not be an issue, as the tape will effectively ‘break’ the reflection, and stand out.

As far as the wiper blades goes, I tell the customer not to use it, or make them aware of the damage it will do. You’ll have less problems if you use a cast because it is thinner.

On commercial vehicle, I take the blade off, and put it in their glovebox.

Either way tho, its a matter of choice.

Hope that helps

This is a bit of useless info but I’m going to tell you anyway.

11 months ago I put a vinyl decal on my rear window (outside) I use my wipers everytime the rear window gets wet (so hundreds of times)

Decal is still perfect.

Problem is the decal was a gift from SA when my boy was born and have no idea what vinyl it is 😕

told you it was useless information :lol1:

I don’t think so, not here at least. Oracal 751, 3M 7725 or Avery A900 is the 3 I use.

[ELTEL666]

What is the deference between cast and not cast, and what jobs would i use ether one for ?
Thanks

[ELTEL666]

I lettered the back window of my wifes Citroen C2 with silver vinyl which was also domed!! – had no problems with it coming off it has been on a year now.

I always put vinyl lettering on the outside of the window, like Shane has said it is far more visible on the outside and lets face it this is an add for someones business so they want it to be seen all the time.
The other problem you may have putting it on the inside is if the rear window is tinted. If there is quite a dark tint on the rear window you aren’t going to see it at all.

Another thing to watch is what colours you use as dark colours won’t really show up without a light coloured outline.

Jac vinyl is a manufacturers name I believe like Oracal or Avery, they will sell both cast and calendered vinyl. A good guide is how much it costs. Cast vinyls cost more than calendered. Ask your supplier for samples.

3 -5 years? I doubt it’s cast.

You use cast for difficult jobs like compound/concave curves, or jobs that need to last in mint condition longer.

Cast generally holds up much better than Calendared. But, it can be harder to apply if your not familiar with how it sticks. Bubbles come out quicker, it settles in the heat better with less chance of shrinkage or tenting.

Its also dearer.

In simple terms calendered vinyl is like a big blob of vinyl forced thru a series of rollers until it is thin and flat…consequently it has slight variances in thickness and suffers from a ‘memory’ that says "I’m really a big blob" . Consequently these vinyls are generally not as conformable and have a tendency to shrink to a greater or lesser degree.

Cast vinyls are liquid vinyl poured (cast) onto a tray and consequently have a thinner, more even thickness and no memory. The process is more costly and this is reflected in the cost (you get what you pay for!)

The high performance calendered vinyls are fine on flat and mildly curved surfaces..but anything slightly compound or with significant indents – use only true cast like avery 900, 3M or Macfleet etc.. They do take more effort to apply perfectly, but it is worth learning the right methods. Our experience with HP calendered vinyls like Oracal 751, Avery 700 series and the like here in New Zealand is that they are fine for the first year or so…but after that, I reiterate ‘YOU GET WHAT YOU PAY FOR’

Here, we would probably use 751/700 on a vehicle window (we are not allowed to do car or station wagon windows here because of our bizare land transport regulations)

Hope this helps
