Fitting Naca duct to nosecone

I have a Naca duct to fit onto my nosecone.

HOw best to fit the straight duct into the bent profile on the nose?

When i offer it up from the inside, there is a gap of up to half an inch in the middle...

Suggestions? Its an ABS Naca duct and a fibreglass nosecone...

OK, put another way, what do i use to fill the gap?

I have a book on car bodywork, and it refers to 'bondo'- whats that then?

Is it some kind of filler? what best to use?

American book then, bondo is a brand name for body filler which like hoover has been adopted as a generic name for all body filler in the US.

Remember that your nose has hisg and low pressure points, though if you want max air, you have to tinker a bit...

Worth reading an article by this guys - not exactly this, but a very related one - where they use a water Magnehelic pressure gauge to prove that you'll have a very high pressure point right in the begining of the nose top apex, then a low pressure one, and another high pressure one right near the windscreen.
