Di-noc size and supplier to cover rear strut brace

[shad0wca7]

Hi everyone. I'll post a proper "hello" later as I've just picked up a nice 03 350z in Gunmetal Grey

 

The rear strut cover has some scratches on it and I've seen people cover it with 3m carbon di-noc which looks pretty awesome. The questions I have are: what dimensions are needed? Where from? How much? Do I need anything else? (e.g the di-noc primer?)

Ebays a good place with loads of size options.
