Its right next to useless. Once there is a boundry layer of oil on the valley walls, the oil doesn't return any faster. All the paint does is slow the heat transfer from the oil to the water via the iron, and POSSIBLY seal off any sand that "MAY" be present.
I haven't painted the insides of a block since high school. Better things to do with my precious time when assembling a motor.
