OXPHO-Blue Creme Gun Blue 4OZ

Works great. I’m impressed

Works well for me for protecting tooling I've made. I'm not interested in matching any particular gun, just making a surface to hold some oil and prevent rusting. Sometimes it comes out a little on the brown side, sometimes more black. I don't know if this is a property of the steel or surface contamination. I also use it for making brushed steel label signs with sheet metal by coating the metal with a layer of black paint, laser engraving the paint away where I want black, and then using this product to darken the metal through that mask. Very nice results, but… some of the paints I've tried leave a residue that greatly inhibits the darkening unless washed off and sometimes there isn't an obvious solvent cleaning the exposed area without taking off the masking. Rustoleum chalk board paint works well. Rustoleum peelable black works well, and if a simple design you can just cut the outlines and peel out the large areas which is much faster. I suspect most dark spray paints work, I just like how easily the lightly cured rustoleums wash off with acetone when I'm down bluing.

I refinish a lot of firearms and I dont always use cold blue, but when I do this is my go to. It goes on thick enough that you dont have to worry about it just running off, it give a deep dark blue on good steel, and is very forgiving. I highly recommend this for the beginner or expert.

Works well. Use gloves or your finish will not turn out at all, and your fingers will turn green. Ajax (or other scouring powder) and scrub brush will remove the green stain (mostly)

Even though this is branded Brownells it is listed as a Generic product. Check the difference in the labels. I purchased both the creme and regular types of Oxpho. The creme type does the best job. I treated a receiver and barrel of a 65 year old firearm that was covered in a great deal of surface rust. The results were amazing. Two people who saw the results thought it had been hot blued. The creme took 3 applications to achieve the desired results.

This definitely yielded both better darkening of steel and ease of use than the liquid BC branded cold blue that I have used in the past. Application is more controllable and cleanup is easier as well. Not a perfect match for most hot blued items, but very close.

I took a chance on this stuff and I’m very impressed. Very even coverage, without bloching. Plenty dark for my needs and the paste is actually easier to apply. Just make sure the metal (steel) is clean.

Works great
