Overpriced without adequate instructions, poor quality

It is like it is. One finds a product that corresponds to the idea of ​​buying, not realizing that other vendors can be found with a little research on the net, which are half the price and still cut precisely to the desired millimeter. The purchase of this product is one of the low points of the last few months, because it is too expensive, there is no clear guidance on how to avoid blistering etc.. Also, there was dirt under the adhesive film, but I have unfortunately noticed too late and so I now have a beautiful, expensive pile that looks somehow cheap. Thank you.

Here are the instructions that I had as much to use:

Plant / Ironing - water spray with a little PH neutral baby shampoo or a tiny drop of washing up liquid fill. Then spray on the adhesive surface of the film and on the surfaces to be glued until everything covered discreetly. Previously, the area is adhered to the course clean.

Applying foil, move until it fits. With a kitchen towel around a thin board wrapped (I got the printer-load used) push out the bubbles. 1-2 twice repeated. Everything with sensitivity (without kitchen towels there are scratches). After about 2 hours again, then leave to dry for 8 hours.

How to do it perfectly.

Too bad that we have to write something so customers. Therefore my advice: go where you get more for your money and check whether the film is clean.
