Hi Ricci;

As a followup and further reassurance, yesterday evening I cleaned the garage including vacuuming up powder, and really stirred it up in the process. I had a floor fan running, and clouds of powder were everywhere. I turned off the fan, waited an hour, wiped down the hull with a tack rag, and ragged on my second coat - No dust the second time! I had a bit of lint from the new rag, but no noticeable airborne dust. When I sprayed finishes, that probably kicked up what dust I used to see. With a brush or rag I suspect it is a non-problem.

Best of Luck, Spidey
