Also, accidental overspray into the cavities will be patchy and rough-looking which obviously looks worse than if it were a uniform coating.
One alternative is to then deliberately spray or paint the inside black, which can work quite well. But it's easier to crumple up newspaper (some people poke balloons through the holes then inflate them) and stuff it in as it can be pulled out again fairly easily. You just need something to stop spray reaching the inside of the back, so it doesn't need to be totally full inside the body.
