Have any of you folks heard of painting bait on the hull of your boat to attract fish? I saw a post on another site and this guy was looking for the stencil kit. I was wondering if this actually worked and since I trailer my boat if the bait would go bad out of the water?

Many of the boats that fish for Sailfish out of southeast Florida paint images of Goggle-eyes, the most popular live bait fish, on their boat bottoms.
At $75 a dozen, which is the going price for live Goggle-eyes, why not? Can't hurt.
I've also seen it done elsewhere with images of Squid.
