Overview

This two-part kit is designed for refinishing firearms when you want a durable blue or black finish without investing in specialized equipment. It suits both professionals handling a small number of guns and home hobbyists working on complete firearms or smaller damaged areas. The formula is intended for touching up worn, rusted, nicked, or scratched factory bluing while leaving intact bluing unaffected, and its stop-and-start application allows additional coats before the developer sets. The 2 oz. kit includes gun blue or black, developer, cleaner, and Disotec XFR oil.

Considerations & Trade-offs

  • This is a touch-up and refinishing kit, so results depend on the condition of the existing finish and how evenly the product is applied.
  • The 2 oz. kit is sized for one or two guns, which may be limiting if you plan to refinish multiple firearms or larger areas.
  • It is designed to adhere to damaged areas while leaving good bluing unaffected, so it is not intended to replace intact factory bluing across the entire surface.
  • The process includes separate cleaner and developer steps, so it requires more preparation than a simple wipe-on touch-up product.
