Overview

This two-part kit is designed for refinishing complete firearms or restoring worn, rusted, nicked, or scratched areas without specialized equipment. It suits both professionals with a small number of guns to refinish and home hobbyists looking for a straightforward touch-up option. The formula is intended to adhere to damaged areas while leaving intact bluing unaffected, and its stop-and-start application allows additional coats before the developer sets. The kit includes gun blue or black solution, developer, and cleaner, with the blue version also including Disotec XFR oil.

Pros

  • Designed to leave intact factory bluing unaffected while treating worn or scratched spots.
  • Stop-and-start application allows additional coats before the developer sets.
  • Suitable for professionals with a few guns to refinish and home hobbyists alike.

Considerations & Trade-offs

  • Best suited to touch-ups and smaller refinishing jobs; the kit is described as ideal for professionals with only one or two guns to refinish, rather than high-volume shop use.
  • The finish is intended to adhere to damaged areas while leaving good factory bluing unaffected, so results may be more localized than a full-strip refinish.
  • The process is described as user-friendly, but it still requires following a two-part system with cleaner and developer, so it is not a one-step application.
  • The 2 oz. kit includes limited quantities of solution, developer, and cleaner, which may be enough for touch-up work but can be restrictive for larger projects.
