Trash
Absolute trash! One star is too much! There are many cold blues that does rust to a point in the process. But I have never come across one that rust after you put gun oil on!
Blue Wonder is a wonderful product!
Wanting to touch up
Bought this for touch up on SW Model18 Didnt start to do as advertisied.Watch all their videos. Repeated the process 6 times with same results.Would not ever buy again! My bootle went in the trash.
Do NOT USE THIS!!!
I started a refinishing project and I am not going to be able to finish it. 44/40 is not penetrating far enough into the metal to actually be worth the prep time. The gun was absolutely clear of original Blueing and Rust I cleared it off per directions on the bottle with alcohol Warmed it up and the result of 44/40 is easily wiped off with oil on a cotton cloth. Trash don't use this product!
Will rust your gun
I followed the directions exactly as directed, including flushing the area with very hot water to "neutralize" the chemical reaction from the blueing. Completely dried and liberally apllied oil. Overnight a reddish brown rust covered my antique shot gun. Like a fool, believing I had done something wrong, I repeated the process with the same results. Very disappointing.
Worst bluing product I have ever used
I got this to use on an old Remington 870 Wingmaster. After taking great care to bead blast the old finish off I applied this product just as the directions stated. I applied a liberal coat of oil as suggested. The next day the barrel and the receiver were rusted. I took all of the rust off and tried again. Same result. I then used my tried and true Vans Gun Blue and the gun now looks awesome. I threw the rest of the 44/40 away. I'd say i wasted a good 4-5 hours because of this product. Stay away from it.
Not recommended...pretty rusty after use
I am supper not satisfied with this GB. It damaged two of my AKs...can turn into red rusty color in two or three days after applied this gunblue on stripped AK parts...This is the worst Gunblue I have ever used...
Rusted my barrel
Used this to touch up barrel on A-Bolt Medallion. Oiled after it was applied, this stuff created heavy surface rust everywhere I applied it. Cleaned and polished the barrel and attempted again with a different gun oil, rusted again. Will never use again.
