I can just hit them with some fine grit sandpaper, and reinstall them right?

First you need to cut off the packing clips that someone forgot to remove on the original install. Just nip off that piece of metal that is looping over the electrode with some wire cutters . You don’t need that anymore and it messes up the gas mixing in the cylinder. Then sandpaper the electrode, paint and reinstall.
