While it's nice to have a weatherproof effect and one coat coverage etc, is there any issues using exterior paint inside the house? The only thing I would be concerned is the mildewcide that is used in some of the exterior paints. Does that stuff spread around in the air or it just means it's not a good idea to eat your food off the walls? <g>
Would it be sufficient to cover it with a interior paint if I choose to repaint the room?
