I don't know where the good reviews come from, but it can't cover small scratches on the Glock 17 at all. Despite following the instructions and applying 5 layers, there remains a delicate "shadow" visible only under bright light. For me, this bluing is very weak.

I bought it 'just in case'. The small package and thus the affordable price allowed me to do so, so I am prepared to prevent all emerging scratches and imperfections. I think that in this form of application, it is easy to use for people with less precision or experience.

Oxyda works quite well. It does the job. It nicely darkened the blade of my carbon Opinel No. 6, Mora Robust, and Mora Companion HD. 📝 Unfortunately, this oxyda works (at least for me) only on knives made of carbon steel...

The bluing works, depending on the type of steel, sometimes better, sometimes worse. Either way, it's worth having any bluing preparation. Factory bluing on airguns is often a joke and wears off quickly, and this product brings it back to a satisfactory state. I definitely recommend this particular product.

The bluing really works, and it was a pleasant surprise :) Worth having at home in case you need to clean and protect an element from rust.

I bought it as part of a kit and it really works :) If I notice some rust and need to clean it, I then restore the coating with this bluing. One small bottle is enough for years.

Blacks well, works both for re-bluing scratches on a gun and for completely bluing stainless steel. After applying a few layers to degreased metal, it looks factory black.

I have to say, the bluing works. I applied it to scratched surfaces on a gun and it does the job. The oxide appears after some time, creating its characteristic protective coating. Now I'm trying to apply a protective layer on my knife. For such little money, I recommend it.

The bluing is definitely recommended, it nicely blacks steel and is very useful for small repairs. Every airgun user should have it in their workshop.

Very good bluing, ideal for small touch-ups. It can also be used for complete blackening, but the color will then be more dark gray than black. To achieve a good effect, I recommend doing it like this: wash the steel object with soap in the sink, then dry it with a clean cloth or paper. Then apply bluing with a brush or cotton pad and leave for 2-5 minutes. Then wash off the bluing with water and repeat from the beginning 3-6 times.

Review for model:

Works quite well. I used it on a blank gun and airguns. It fills minor losses of factory bluing, but I don't know how it will perform on larger surfaces. Important note: The surface must be thoroughly cleaned and degreased(!) before using cold bluing.

It works, maybe not as black as factory bluing, but can be used for minor touch-ups. Very efficient—a small bottle has great potential. Before blueing, you need to degrease the surface, e.g., with acetone (nail polish remover).

Blacks like crazy!! You just need to know how to do it. Black, black, black!! It blacks steel as if it came from the factory, I must say it even blacks aluminum, but only a little :) Regards

It masks small scratches, and that's what this preparation is for.

Good for minor scratches. Remember that such products will never replace the factory coating.
