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. 

I have tried "Infutac" from french Diatex, holds thing in place nicely but leaves fiber trace on the mold surface that has to be wet sanded to remove,
maybe I use alittle to much, or leave in on to long before infusing, dont know, but it has given me a whole lot of extra job.
