Bonding Carbon Fibre to Aluminium

Hi,
   I've bought the carbon fibre naca vent from you which I'll be bonding to an aluminium bonnet to feed cool air to ITBs. Looking through your store the permabond 515 looked like it would fit the bill but I would appreciate some advice from someone who knows more than I do. Additionally how much would I need to bond the duct as its sold in 50ml or 400ml quantities. 
I've also been told I need to seal the aluminium before bonding carbon fibre to it otherwise it would cause corrosion. Is there a specific product for sealing it or can I just use a normal epoxy primer?

Cheers

Aaron

Smile yeah it would be a bit late once I'd cut the hole and stuck it on. So you think further forward would be safer? I could always create a tunnel under the bonnet to make sure the airflow underneath is directed to the ITBs.

Better off further back. However, aesthetics do come into it as you are not building a race car :-) Also, without actual data for your car I can't give you the best location.

The existing vents, are they supposed to vent hot air from the engine bay? (I realise that this isn't your car) Are they OEM?
