Birchwood Casey Perma Blue Liquid Gun Blue, 3 oz.

I liked how fast it was to use. The ease of use.

nothing.

Good value.

Ease of use. Reblueing is all about preparation. More time is spent to ready parts than to apply the blue. Follow the bottle directions

This 3oz bottle should have a swab attached to the lid for larger projects. Using a Q-tip per directions is fine for smaller parts, but a 3oz bottle could do 3 rifle barrels.

Check You Tube for hints and preparation of metal, wear proper latex gloves thru out the whole application, and reapply to get an almost black hue. Follow the directions on the bottle, multiple applications only takes about 15-20 min. but when you get it where you like it, soak in a penetrating gun oil overnight. I lightly used 0000 steel wool between coats, and all parts came out perfect like factory finish. Very satisfied with results.

I tried this on a raggedy old crosman 130. I got as good a result as if I had used rubbing alcohol. Basically nothing happened other than I got the metal wet.

Make it actually work.

Not sure what happened axactly but this stuff did nothing on the gun I tried it on.

Easy to use.

None

Very good for touch ups

goes on very easy.produces nice finish if barrel polished well.changes color quick and can get very dark and shinny.again barrel must be finished correctly

bigger bottle and better absorbing swabs

works best on a whole blueing job for even color.plug ends of barrel and heat barrel in hot water or even a hair drier.works best if gun very warm.before two hours polish out with 0000 steel wool and color will blend together great.barrel must be very clean and highly polished for best effect.wear rubber gloves to keep oil off barrel when coating.

Good for spot repair of small rust patches. Works very well with 00 steel wool. In fact the later is almost a necessity to get a bright finish. As others have mentioned, do not use 3-M Scotch-brite unless you want to remove the previous blue finish. Multiple coats are required to get a deeper blue finish. In comparison with the paste, the paste gives a deeper blue on the first coat, but the liquid seemed to give the deeper blue coat after multiple applications. Completely re-blues a Savage 22/410 shot gun barrel - in my estimation it will take several more coats to achieve the darker finish desired. Very close to matching the finish on a High Standard Model 102 after 6 coats. The later was a spot repair job. Almost immediately matched the finish on a Crosman Model 700 .22 caliber pellet rifle on the first coat. Again the later was a spot repair and a second coat was applied. Spot repair on a Remington 511 Scoremaster took 2-3 coats to match.

Make it less hazardous

The obvious, preparation is 90 percent of the work and patience is the remainder.

Seems to work well.

It's not magical...it does not eliminate the missing bluing...but it protects the 'once-exposed' area.

Based on label...highly toxic.
