I agree with Cory, that'll be a black line, leading to a kick-in step I would think. I believe there are a number of detailing parts available for the Corsair; cockpit, wheel wells and engine. I'm not much up on aftermarket things, but I think they'll be from Eduard, Signal or Aires. I've certainly seen ads for them in the modelling mags in the past.
