Hi I have been looking at this Air Box and trying to figure out how I can Vaccum Bag ??? to me looks impossible, so any help appreciated, Regards DM

Yes I have tried it, which is why I advised you against it. However, I also know how to use it because I didn't spit the dummy when my first attempt with it didn't work, so I know exactly why Matt would recommend it to you - it does work when you get the feel for how it behaves. I have a full roll of it in stock in my workshop because it can be very useful for many applications. 

From the very start, everyone has been telling you that this was an ambitious first project. Even with easier to use materials, this was an ambitious project for someone who doesn't know what they are doing. Most people might take that on board and have a play with the materials they've got on something smaller and easier so that they don't waste £1000 of materials, but you were stubborn and you got bitten. Just deal with that and move on, dont attack the people that tried to help you.
