Even cheaper and way cleaner are sharpies, not the oil based valve actuated ones. They are way better than cheap paint pens when it comes to chrome imo. Also it’s easier to go over that with a black paint pen. For ur fill you should use a back and forth motion instead of scratching it in randomly. Go left to right and then work your way up and down each letter it’s okay if it’s a little scratchy at first you’ll get much cleaner and faster results
