Thanks for the advice here. It is too easy to jump into buffing, sanding, polishing, etc with the exuberance that seems uncontrollable.

What about something like THIS from the same site you've linked to for the buffer to sit in, then have the hose hooked up to a powerful shop vac outfitted with a true hepa filter?

My shop vac has a true hepa filter that I've outfitted it with and I use drywall dust collection bags inside the vac. I've done this for years. Incidentally, "HEPA" in relation to filtration terminology is good, but "TRUE HEPA" is IMO the "real" HEPA filter, the kind that filters 99+ % particles down to let's say .7 micron. "HEPA" filters can be as inefficient as only filtering out around 60%.

I've also thought about buying THIS even though it's pricey, as you've said, it's much cheaper than a funeral or oxygen tanks later in life? Currently I use a two canister filter face filter mask, but it's bulky and after a few hours, it becomes quite uncomfortable.
