but may look odd against a real carbon fiber grill!
....Exactly what I think.
But it would look very good and subtle on a black car, just as real carbon does. But consider it very carefully and get a supplier to lay out a big sheet of it across your bonnet to show you first, and in outdoor light conditions.
The bonnet area, being a skyward facing large surface, will show either carbon vinyl or real carbon at its worst in some lighting conditions - Either as a material some would view as fake (vinyl carbon) or as bling and over sparkly (real CF). Also the bonnet is traditionally a real carbon component and the expectation is for it to be real.
I think that where you use the carbon vinyl on a car exterior is critical to the message it gives.
Used externally on the
whole car looks far more 'honest' and cool, imo.
