PREPAINTING NAIL HEADS
When you’re installing prepainted wood or engineered-wood siding, paint the tops of galvanized nail coils the color of the house before loading them into the gun. It’s much faster than going back and painting them one at a time later. Use a foam brush and apply the paint sparingly so it doesn’t drip over the edges of the nail heads. Let the paint dry completely before loading the coils into the nail gun.
