I have little experience with photoetched parts, OK none.
What's the best way to paint a 1/35 engine screen without clogging all those tiny holes? I seem to remember something about soaking the brass in vinegar overnight if you just want it to turn black. Should the metal be primed before using model paint? Is enamel better for metal than water based? An article in FSM like "Everything you ever wanted to know about Photoetched Metal" would be nice.
