Man as I read the introduction these serious came to mind, could not have said it better.
Even after hand sanding, then learning the greaseless, I've come back to hand sanding as a focus. Crisp lines, and less chance of screwing up. Also a Dremel its very useful but also great care is needed with. Bounce around with tools in your process and don't hesitate to stop and re-focus your efforts as not to screw.
***Right a check list until you become proficient!
That's great, the rabbit hole, it really is deep! Seriously. Lol
