Fixing runs with a nylon stocking

I was reading an old post on an American site of which I am not a member. Anyway, the guy made an off-hand remark that when you get a run while spray-painting you should fix it with a nylon stocking. What on earth is he talking about? Is this some secret way of fixing runs? Never heard of it. I'd love to know more if it is.



Anyone know what he is talking about? Is this about lacquer ?
