Generally the ones from Windstone (almost used up) should be reserved if you just need a tiny bit to do a repair or touch up. If you need enough to do a few PYOs, etc, it’s probably best to buy one. Decocolor paint pens in any metallic color you prefer are the way to go. The large chisel tip is what you want, even though it seems you’d want a fine point. The wide calligraphy or chisel tip works perfectly on the raised bumps on the statues to accent them. I have also used the Krylon brand metallic paint pens in the past and they also work well.
