No. I would remove the sparkplug and fill the hole with paper towel or a piece of clotch. You could use an old spark plug but you don't want paint on the one you plan to use.
If you still have the chrome acorn nuts that came with your engine this would be a good time to replace them with shouldered/flanged hex nuts. The acorn nuts are pretty but have been a source of trouble for many in the past. Remove the nuts and protect the stud threads with masking tape prior to spraying the paint. When the paint is dry thread on the new nuts and torque them to 120 to 140 inch pounds using a cross pattern.
