Signal,
Artifact is a bad, bad no-no. Even if it wasn't, I would be too damn conceited to allow any mistakes that I can prevent by simply flipping on an obnoxious paint job for a minute and giving it a once over. Sometimes, having bad source material cannot be avoided- especially on ships that didn't have a long pre-war or post-war existence- but stray pixels are too easy to fix.
There are few things I want to be perfect- my hand-loading is one of them, these ships are another.
