Considerations & Trade-offs

  • Designed for touch-up or complete re-blue, so results depend on the condition and preparation of the existing steel surface.
  • The 3 fl. oz. bottle is a small-format option, which may be limiting for larger refinishing jobs.
  • It is described for polished steel that contains nickel or chrome alloys, so it may not be the right choice for every metal surface or finish type.
  • The product is a cold blue solution, which makes it a finishing product rather than a replacement for full refinishing work.
