1/350 aircraft tow bars: To paint or not?

I was thinking of scratch building some 1/350 scale aircraft tow bars for a carrier from very thin styrene strip. Since the styrene strip is white, would there be any need to paint it or not? If I don’t paint the tow bars, will the bare white styrene get discolored over time?

1/350? Adventurous! If you’re concerned about them discoloring, just give them a quick shot of white primer.
