Can Carbon Fiber Engine Hood Be Spray Painted?

The main consideration is the original flatness of the hood. If it is not flat, a lot of putty needs to be applied, which will greatly increase the weight and burden of the hood.
If your carbon fiber engine hood is just a decorative cover and not lightweight, it is possible. If it is a lightweight carbon hood, doing so has no meaning at all.
The carbon fiber engine hood needs to be painted mainly with primer. If not handled properly, carbon patterns will appear soon.
