glazing putty and moisture?


New Hunter
hey folks,
working on my first set of armor, printed. Ive been sanding the print lines down and filling w bondo glazing.
so far, so good. but Im at the point where some pieces are going to need wet sanding to get to the "metal smooth" look.
ok, so wet sand. and i do have a little exp w that. but my q is, I know regular bondo absorbs moisture, so i figure the glazing will as well. so if i wet sand it, what would be a good drying/proofing time before further work? throw it in a bag w dessicant?
Ive never messed w bondo glazing, or on something this small and detailed.
