very dark gray interior paint
Here's a hairbrain sounding method I,ve done long time ago with interior rattle cans::: get an equivelant can of black spray paint shook , tested & ready to go. hold cans next to each other with both hands & spray both as same time pointing at same area as if they were 1 can. Or as you're spraying with one, come right behind it with the other.
Yea, it's an art form to accomplish, but it can work with good spraying skills. Sample time?
