Managing contamination when car window tinting

This post addresses issues you may be having with contamination.

I found the best way to deal with this is to increase my water usage.
Be careful when tinting newer cars though or anything with electrics in the doors , if in doubt dont flush down the windows but do a dry install with extra slip in mounting solution.

When flushing, I have now worked out that de-ionised water works really well, use it in a clean spray bottle, flush down with this first then give a light mist with your mounting solution on the glass and really soak your film well. There are lots of videos online about car window tinting and you can pick up a few good tips from watching these.


Heat Shrinking with Soap

One of the most difficult techniques to master when you start out in the car window tinting business is heat shrinking rear windows. When i started tinting window 10 years ago, one of the most difficult things and for sure the biggest obstacle standing in my way was heat shrinking back windows.

I started off with the the dry shrinking method, here you use talcum powder wiped onto the rear window, this was a method I found hard to come to terms with, but I persisted and could do most windows using this method. I did get the odd crease or two and this was very annoying as it meant throwing that piece of film in the trash and starting over again!

 Fast forward a few years and a guy called Mike Williams in Texas discovered a new method of shrinking using soap, regular hand soap, the velvet type variety was the best.
You rubbed your soap on a rag and then smeared it onto the backglass, let it dry or heat it with a heat gun and you were ready to shrink.

OMG!!!..this method blew me away!! could use a felt squeegee and smooth the film, you didn't need to wet check the window after you had shrunk it, it was much cleaner than the talc method and the finished window was a very snug fit.
If you are just getting into car window tinting, trust me this is the method you need to master, forget wet shrinking or powder shrinking, the soap shrink really is the bomb!


Minimum tool requirements for tinting windows

Here is a list of a few basic tools that you will need to carry out just a simple car window tinting installation:-

Olfa knife with stainless steel blades!!!
black turbo Squeegee
White Max Squeegee
Lil Chizler
Wire wool 0000
White hard card
black hard car
masking tape
heat gun

I think with just those few tools i could get buy and tint most car windows, you dont need a tonne of tools like a mechanic, keep it simple and uncluttered.


Stopping Contamination in your window film!

Contamination.. this will ruin your job and break your heart!!
It's a pain in the butt for all window installers, the more experience you have the less of an issue it will

One of the best things I ever did to reduce contamination in my jobs was to make the switch to buying bottled water, combine this with a regular cleaning process for your spray bottles and you should notice a marked improvement in your installations.

Dont be afraid to flush your windows down just before the final installation of the film, be careful on the more modern cars as they have a tonne of electronics on-board nowadays, you could be letting yourself in for a costly repair if you are not careful.

Use masking tape to tape off the felt seals at the edge of the glass and also on the roof liner.
I have fought the battle with contamination for many years and still do. Its something that you will lay in bed at night wondering how to stop it completely.

I have a few other good contamination busting tips I will share next time.

car window tinting - heat shrinking

today I'd like to talk to you about technique known as heat shrinking.
this technique is used to form the film with heat on curved windows, It takes a long time to master. Start by cleaning the back window of the vehicle, then using some ivory soap on a wet rag your place over the back window like to dry.

lay your film on the back window, using a heatgun, shrink the fingers, you can only shrink these fingers in vertical direction.

Be careful not to burnthea window film, carry out this procedure across the whole window until the window film fits like a glove.

using a bright light on the inside of the vertical cut out your film pattern on the back window carefully with a stainless steel blade.

practice this at least 100 times to become confident with this method.

I will add more information on the subject in another post.


Car Window Tinting - The Basics - Pattern Making

One of the first steps in car window tinting you must master is pattern making.
I will give you a few ideas of how I make my patterns and show you how to do this without cutting with your Olfa knife directly on the car.

We will start with cutting a pattern for a fixed window, this can be a static quarter glass or back window.
This one little tip will potentially save you from future hassle.
Once you have shrunk your pattern to the shape of the window, then we need to cut the pattern , in this example we will assume the vehicle has a dot matrix area around the edge of the window.
Instead of just cutting directly on the car, use either a small piece of the plastic tape, the sort of tape they use to wrap around cardboard boxes for transporting them or use a thin button as used on a small child's piece of clothing.
Slide the tape or button under the film and sit the blade of your knife onto the button/wrapping tape - then cut out your pattern. As you will be sliding the button/tape along the glass with your blade, your blade will not have contact with glass directly and will stop you potentially scratching the glass and will extend the life of your blades.

This tip is one you should certainly introduce into your pattern making so you can cut your patterns quickly and without any risk of scratching the vehicle glass
