Description
Bluing a firearm at home used to feel like something reserved for the pros, but the Birchwood Casey Perma Blue Paste Gun Blue Kit takes the guesswork out of it. This is one of the most trusted names in cold bluing, and the paste version is the one to grab when you want a richer, more built-up finish. The paste clings to the metal a little longer than the liquid, so it darkens slower but rewards you with a denser, deeper blue-black once the job is done.
What makes this a solid pickup is that it truly is all-inclusive. You get the paste plus everything needed to prep the surface first, which is where most bluing jobs succeed or fail. The included cleaner-degreaser strips oils and residue, the blue and rust remover takes off old finish and corrosion without eating into the base steel, and the fine steel wool lets you smooth things down between passes. Skip the prep and you'll get streaks, so it's nice having the right stuff in one box.
What the Perma Blue Paste Kit Handles Best
Think touch-ups on holster wear, faded barrels, worn edges on a carry gun, or a full reblue on an older rifle or shotgun you're bringing back to life. It works on properly cleaned, rust-free steel, so blued and carbon-steel guns are its wheelhouse. Keep in mind it won't blue stainless, aluminum, or other non-ferrous metals, so match the kit to the right project.
Getting a First-Class Finish with the Perma Blue Kit
The 2 oz tube of paste goes a long way and is sized for multiple touch-ups, so one kit can cover several small jobs or one larger project. The Barricade rust protection wipes at the end seal the deal and keep your fresh finish protected. A complete instruction guide walks you through each step, which is handy if this is your first time doing your own bluing. Take your time on the prep, follow the steps, and the results genuinely look like something that came out of a gunsmith's shop.

Frequently Asked Questions
What's the difference between the Perma Blue Paste Kit and the liquid version?
The paste is slower to darken than the liquid, but it builds up a denser, deeper finish as you work it in. If you want the richest blue-black and don't mind taking a little extra time, the paste is the way to go. The liquid is faster acting and better suited to quick, even coverage over larger areas.
Will the Perma Blue Paste Kit work on stainless steel or aluminum?
No, this kit is made for carbon and blued steel only. It won't take on stainless, aluminum, or other non-ferrous metals. For those materials you'd want a product formulated specifically for them, like an aluminum black finish.
Do I need anything else to reblue a gun with this kit?
The kit is designed to be all-inclusive, so it comes with the cleaner-degreaser, rust remover, steel wool, applicators, and rust protection wipes along with the paste. The biggest thing you'll add is patience and thorough surface prep. Clean, rust-free metal is the key to a streak-free result, and the included instruction guide walks you through the process.
How much can I reblue with one Perma Blue Paste Kit?
The 2 oz tube of paste is sized for multiple touch-ups, so a single kit can handle several small jobs like holster wear and worn edges, or one larger project like a full rifle or shotgun reblue. A little paste goes a long way when it's applied correctly. Just remember to prep the surface properly for the best coverage.
