I would def use a satin finish on the dash area, it has less glare. for the door panels I like the satin aluminum look on a black interior. like you said, too much black inside makes it a dark area and light gets sucked up. you can't find anything you drop. I would suggest to do a clear on the bare aluminum, if you go that route, so it doesn't rub off on everything and then have shiny spots or leave your elbow black. a lighter shade of charcoal may offset the black well too.
nice job on the beading, looks great. do you use a soft roller underneath, like a skateboard wheel or something? Lazze had a video that showed him doing a motorcycle tank side where he used that technique with what looked like a fairly pointed upper die, like a tipping die.
