I only skimmed the posts after your first, because I have to cut short, but I recommend using rattle cans to paint your Black Widow, rather than hand-brushing, and masking as necessary.  Hand-brushing is not impossible, and it doesn't automatically lead to less than optimal results, but I think if you're starting out, spraying might be easier for you.  It was for me.  And if you do want to move to an airbrush at some point, some of the techniques are very similar, because both methods use air under pressure to apply aerosoled paint to the surface.

Just my mustard, as the Germans say.
