Okay, I carefully washed off the plane, blew compressed air over it from the airbrush, and then painted it in a spraybox that has enclosed doors. And I still see tiny bits of hair-like dust in the finish. Darn it.
Is there any careful way to remove it? The only think I can think of is to use a very fine sand, but that will ruin the perfect finish I want.
Or is there no such thing as a perfect NMF? Sigh.
