In video tutorial How to Make a Carbon Fibre Car Bonnet/Hood - Part 2/3 at about 03'22' you are using a spray that helps you to maintain the fabric. 

Hi I have a good story about the spray adhesive, seeking Stayz discovered that the distributor for Europe was less than 70km from my city, I contacted them and they said they had saved hundreds of spray they could not sell because they were defective, that if I wanted to try them gave me one. When I visit his shop to catch the spray. Indeed its spray is defective, to used once, the next day it was all stuck and useless. From then probe different products and brands, it is certainly my choice spraymount 3m, and I have made many infusions and the result is perfect, even among gc50 gelcoat and the first layer of carbon fiber.
