So, while the bluing itself does not improve rust resistance, a properly oiled blued surface does. But you can't skip the oil. Wipe it down once a month or after cleaning and use, with enough to just darken the surface and turn it glossy. **Q: Will this darken nickel plating?** A: Hi, I haven’t tried, but in my knowledge and research I believe it will not... you could try to contact the company? Nickel is a different chemical mixture than most materials. We use it on steel guns from holster wear. **Q: Will it turn brass blue?** A: Birchwood Casey has a Brass Black https://smile.amazon.com/Birchwood-Casey-Brass-Finish-3-Ounce/dp/B0000C514O/ref=sr_1_33?crid=8PKKSQSHII7L&keywords=birchwood%2Bcasey%2Bsuper%2Bblue&qid=1648750227&sprefix=birchwood%2Bcasey%2Bsuper%2Bblue%2Caps%2C99&sr=8-33&th=1 **Q: Does this work on Sterling Silver?** A: It doesn't say, it doesn't work on stainless steel is what it says. Basically what this chemical does is slowly rust metal and stains to give it the bluing effect. Sterling silver doesn't rust but the blue stain in this might change the color but not like a steel firearm. Hope this helps. ## Frequently Bought Together - Birchwood Casey Fast-Acting Long-Lasting Spanish Perma Blue Liquid Gun Blue for Steel, Touch-Up & Complete Reblue, 3 FL OZ (90ml) - Birchwood Casey Fast-Drying Fast-Acting Aluminum Black Metal Finish for Restoring Scratched and Marred Areas, Gun Cleaning - Homax 10120000 Steel Wool, 12 pad, Grade #0000, Rhodes American, Final Finish --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/140555824-birchwood-casey-fast-acting-long-lasting-spanish-super-blue-liquid](https://www.desertcart.jp/products/140555824-birchwood-casey-fast-acting-long-lasting-spanish-super-blue-liquid) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-11*
