Haven't used the In&Out much yet. I didn't try it on the wire looms because of the instructions on the can:

"Spray 10-12 inches from surface in quick spurts. Do not spray any closer or in longer, continuous sprays. Wait 10-15 seconds before wiping, rubbing or buffing."

I guess it doesn't say you have to wipe or buff, but that's what I thought it meant... Live & Learn, I guess.
