Brownells Dicropan ''Im'' 1 Quart

Brownells Dicropan IM is a cold-process bluing solution that lets you refinish gun metal without the complexity and hazards of hot-salt systems. Whether you're a gunsmith running a full shop, a small operation doing occasional work, or a serious home hobbyist, this 1-quart container of Dicropan IM gives you a controllable, repeatable way to achieve a professional blue-black finish on steel parts. Unlike caustic-salt methods, you can set up almost anywhere with minimal equipment—just a couple of tanks, a heat source, and the chemical itself.

The real advantage here is simplicity and safety. Dicropan IM contains no caustic compounds, no mercury, produces no odor, and generates no harmful fumes. That means you can work in a garage, small shop, or basement space without the ventilation and safety infrastructure that hot-salts demand. The process is straightforward enough that you can repeat good results every time you use it, and the formula is stable and economical over many jobs. It's especially valuable for work that hot salts would damage—like soft-soldered double-barrel shotguns that can separate under extreme heat.

Each quart comes with complete instructions to walk you through the procedure, so you're not guessing at timing or technique. If you want a commercial-grade finish without the commercial-grade headaches, Dicropan IM is a smart choice for any level of gunsmith or enthusiast who takes finishing seriously.

Frequently Asked Questions

What equipment do I need to use Dicropan IM?

You need a couple of tanks and a heat source. Because it's a cold-process system, you don't need the extensive setup required for hot-salts bluing, making it accessible for home shops and small operations.

Can I use Dicropan IM on soft-soldered guns like double-barrel shotguns?

Yes. Dicropan IM is safe for soft-soldered firearms because the cold-process method won't expose them to the extreme heat that can separate solder joints in caustic-salt bluing.
