Will I kill the value of my Demon

If it's original paint in good condition, I wouldn't do it.

I'd especially not do it if it's an F6 interior.

So the paint is ok at best, it had two quarter sized holes in the rear quarters and someone patched them and primed them.
The interior code is f4f6 so from what I gather luxury interior with split bench in green.
