How much materials would I need to make a mould of my Audi A5 bonnet (hood)? I'm looking to make a carbon bonnet for it and it will be my first project. I have seen the kits on sites but I'm not sure on how much of what it is I would need. Any help will be appreciated. Anthony.

You'll need a big kit. Without knowing the exact dimensions of your bonnet it's a bit difficult, but at a guess I'd estimate an A5 bonnet is somewhere in the vicinity of 1.5 sqm. So you will need somewhere around 1kg of tooling gelcoat, around 500g of vinyl ester skin coat (assuming you use EC's 100g CSM for that first layer), and somewhere between 13-15kg of tooling resin for 5 layers of 450g CSM. Not sure how big EC's kits are, but I'd guess you can probably get 1kg cans of the tooling gelcoat and skin coat, and a 20kg barrel of the tooling resin. 

Thank you for your reply. I will start to price up what you suggest. Is EC the best place to get materials from or can you recommend anywhere else?
