Mr. Black

Found this guy selling pre-cut tint on ebay. Is it hard to install on the back window an is it easily torn. It can't be any harder than the clear bra to install right?

The materials are different, but the concept is the same. If the tint rips that easily then it's probably cheap crap.

If you ever wanted to try to tint a back window yourself, the Z is a pretty good car to try on and get the basics.

Basically, it works like this.

Film is produced in flat rolls, but many pieces of glass have some sort of curvature to them. In concept, take a piece if paper and try and lay it flat on a balloon. It won't, and you get what the industry would call "fingers". This is where the tecnology of the films come into play. Years ago, you used to see "strips" in the back window. This is because of the curve of the window, which determines the amount of "relief points", or in the case of strips, the thickness of the strip before the occurance of "fingers".

Now you see what they call "one piece" windows, which is an industry standard that typically denotes the experience and talent of the tinter. The reason for this, is the newer films allow what they call "heat shrinking" (taking a heat gun and actually controllably melting the film to form to the curve of the window). This is NOT an easily learned technique and takes alot of practice to do well, and many years to master.

Now, in reference to clear bra, it works the same, but the materials are different. Typically, clear bra materials are easier to shrink, but more succeptable to over shrinking and melting. Some clear bras you can shink slightly with the heat from your finger.

But ALL films can only shrink so much before they melt and are unusable.
