Great Results!
For years I have been fighting light rust on my matte finish Remington 700 SPS. No matter how much I cleaned and oiled the finish, the light rust would return after a relatively short period of time. Making matter worse, this rifle was submerged for 2 days in 2016 when my home flooded. Immediately after the flood, I cleaned and oiled this 700, but the finish was degraded a bit. Finally, I decided to "reblue" my Rem 700, and I chose Brownell's Oxpho-Blue for the task. After stripping the old finish to bare metal, I made 10 applications of Oxpho-Blue using the following steps. 1. De-grease using brake cleaner 2. Warm part being blued 3. Apply Oxpho-Blue per manufacturer's instructions. 4. Wipe off excess 5. Burnish lightly with 0000 steel wool 6. Blow away remaining steel wool fragments using compressed air. 7. Rinse with water 8. Dry using isopropyl alcohol and gentle heat. 9. Repeat steps 1 - 8 As a final step, I coated the rifle with a CLP product which leaves behind a dry protectant which owners of Remington matte finish firearms claim stops the recurring rust issue. The result is a consistent, even, dark, and rich finish that looks better than the original Remington "RemRust" finish ever looked. Since the chemistry of Oxpho-Blue provides a finish that is somewhat similar to a Parkerized finish, I anticipate it will be durable and wear resistant. Time will tell ...... Time will tell.
Was skeptical but now a believer
Have to admit I skeptical at first after dealing with numerous other blueing products but now Im a believer. After acquiring a decent FN Mauser the metal needed to be touched up but I was weary about doing it but after hearing about this product I decided to try it. Read the directions and followed them and after about 5 or 6 times the pieces needed to be redone are a deep blue. I did find out that if you heat the metal a little the products works a bit better and speeds up the process. Over all this product works and works well and will cause one to touch up rifle after rifle till 8 hrs later every rifle you own is re blued and touched up and your spouse is yelling at you for not helping with the kids or dogs.
Bluing for the average gun owner
The product did what was expected without mess or anything additional.
It actually IS amazing stuff.
I have an Alpha Marksman V4 slide that frankly has a thin, easily damaged finish. I got a pretty good scrape on the rear of the slide when it came off my workbench and nicked a piece of my drill press stand. The stand is coated with an enamel finish and was not marred, but of course, the slide was, with a 1/4" long jagged shiny silver metal now showing through. I never have used Brownells Oxpho-Blue; the other blue I'd used was in a tube and didn't really do a good job and was difficult to mess with. Thanks to the reviews here I got a 4oz. jar of the Oxpho and used a Q-tip with alcohol on one end to clean the oil off and the other end to dab on the slide's scrape. The scrape turned from silver to near-black in literally seconds. I wiped off the excess and dabbed it a second time. Wiped off, let it dry, re-coated with oil and it looks great! Only I can find the original scrape due to the slight outlines in the supposed DLC original finish. My goof is gone... I'd give it 6 stars if I could.
great bluing agent
This is the best bluing agent I have ever used. I did a 100 year old shotgun and the barrel came out with that nice deep blue finish.
Outstanding coverage
I have been using oxpho-Blue for about 30 years. I not only use it for gun repair, but also use it for layout work. It even works well on highly polished surfaces.
Great way to blue inexpensively!
I use Oxpho-Blue when refinishing an older firearm that the customer doesn't want to go for a more expensive finish. When done correctly the blue/black finish is really nice.
1911 Build
I used this on a carbon steel frame for a 1911 build(my 1st build). First I polished the flat surfaces moderately and left the matte surfaces alone on the frame. A 4 oz. bottle is plenty. I used 4OT steel wool to rub it in after applying with cotton ball. Three coats, then sat in ziploc bag of oil for 2 days. I rinsed between coats by pouring hot water on the frame. I ended up with small stains on the flats. I then lightly sanded flats again, applied 2 coats, garden hose rinse between. Forcefully rubbed OB in with 4OT. Coated with Hoppes gun oil overnight and sat in open air. Don't bag and a do a high pressure rinse I think were key. Front strap was too smooth so it looks glossy. Should have "roughed" it up with 320 grit. The flats are a deep dark bluish black. To the untrained eye it looks as good as a factory bluing. The scale that forms after each coat is hard to remove well inside magwell area, holes, trigger groove. Get creative. Tiny wire brush. Use non scratch scotch brite. Would use again! Absolutely!
Good Quality Cold Blue
Heat the parts before applying Oxpho Blue. Card off the scale and reapply, heating between coats. Works well on screws, pins and touch up after filing or polishing parts.
