Using Your Liners as Patterns

This week's tip:

I have been saving my liner's from various vehicles that are kind of difficult to cut the pattern on and filing it away for future use. This saves alot of time because we don't have to cut on the car, especially those that have a rear spoiler on the roof like the Mazda Protege5, WRX wagon, GTI, CRV, Matrix, Land Rover Discovery, etc. (just to name a few)
Just file it away alphabetically like you would do with your paperwork. When one of these cars come in, just pull out the pattern and pre-cut it on your glass table. Make sure you cut it just a little bit bigger so you can heat shrink it. After the film is form fitted, trim off the excess, if any, and install.
You can also keep the rollup windows and quarter glass liners if you'd like. This could save you some valuable time once you get use to working with the liners.
I could post some pictures but didn't think it is necessary.

This is exactly the way metinted beginning in 1980, using patterns. Of course the first had to be cut from film or butcher paper, but I always kept the liner, filed 4-5 sets per 20" film core(s) stacked on shelving, label them, and recorded on clipboard paper.

OK here is how I go about it.
A car is booked in...say a current Rav 5 door.

I dig out the retained liners from a previous filed and tinted Rav.

I then lay the side windows and rear screen of the Rav out on a 60" roll of film just like dress makers do.
I trace out rough freehand all the film required to do the install, flicking over passenger to driver side films so that they are on top of each other. I wet down both films so that they don't slide around for cutting on the bench and use the liner pattern.
I cut both horizontal and verticals "exact" off the pattern but make the top half an inch oversize.

Now 2 variations of the install can be done at this point. One is to remove the liner (file away again) and put the film in duo mode to the glass held on by water and tacked on by the squeegee. Pressure just holds it there in the centre. Calculate how far you want it under the door trim (panel nearly always removed) and cut the top edge by using your blade to scribe the precise curve. Presto done ready for fitting.

The other alternative is to go back to the half inch oversized top and rather than pre-cutting both film with liners intact, install individually and cut the top of the film whist it is on the glass. The only slight risk here is with dirt that may come over the top of the edge when cutting. This is the way most speed freak tinters appear to tint downunder because it eliminates a bit of double handling.

Hope that is clearer.
