Frequently Asked Questions
Can Perma Blue Paste be used for a full re-blue or just touch-ups?
Perma Blue Paste is versatile enough for both. For small scratches or worn areas, apply it directly to the affected spot for a seamless touch-up. For a full re-bluing project, strip the old finish, polish the metal to the desired sheen, and apply multiple coats of the paste — carding lightly between coats — to build up a deep, uniform blue-black finish across the entire surface.
What types of metal does Perma Blue Paste work on?
Perma Blue Paste is formulated for use on most steel firearm surfaces, including barrels, receivers, bolts, and actions. It is a cold-blue product and will not produce the same depth of finish as hot-tank bluing, but it delivers excellent results for home and field use. It is not recommended for stainless steel, aluminum, or polymer surfaces, as these materials do not react with cold-blue chemistry.
How should I prepare my firearm before applying Perma Blue Paste?
Proper preparation is key to achieving the best results. Thoroughly degrease the metal surface using a quality solvent or degreaser to remove all oil, grease, and fingerprints — any contamination will cause blotchy or uneven bluing. For touch-ups, lightly polish the area with fine steel wool. For full re-bluing, polish the entire surface to your preferred finish before application. Always handle prepared metal with gloves to avoid transferring skin oils.
