That's what
#dsbrantjr was mentioning, the cotton ball will likely snag on the wire.
Did you pump your tube up till it ballooned up really big? On a really slow leak I'll use half a kitchen sink of water, and I've had to run my hands along the tube a section at a time to get trapped bubbles from the submersion process off. When you watch a bubble grow where nothing was there before, that's a dead giveaway.
BTW, ballpoint pens are a good way to mark slow leaks like this. X or * the site so you don't lose sight of it.
