Review for model:

The product works well for covering small surfaces and masking minor scratches or worn spots with multiple applications. It is not suitable for oxidizing an entire weapon. I recommend the product and the store Militaria.pl.

Very useful bluing, but only for minor touch-ups. It doesn't give perfect black, slightly mattes the surface and reacts with heat bluing, so it needs to be applied precisely. Its durability is average.

It is great for minor touch-ups, scratches, etc. Easy to apply, hardens quickly. We'll see how durable it is over time, but at this price, there's nothing to complain about.

The bluing works well, it's not hot bluing but for small elements it's perfect. For the proper effect, you need to apply at least 5 layers in the following way: 1. Degrease with acetone 2. Heat the item to 50-60 degrees 3. Apply the bluing and wait 1-3 minutes 4. Rinse with water 5. Repeat the process for a minimum of 5 coats At the end, after drying the item, you need to grease the spot with gun oil to deepen the black color and give shine.

Masks minor scratches.

Used to refresh an already worn airgun and the effect is really good.

I recommend, as described.

As described.

I blued a military knife with already worn spots of bluing—the shade is a bit different, but I didn't want to remove the remaining factory bluing. The capacity is rather small, but I recommend it.

Small capacity for small scratches. The shade of the bluing differs from the factory one. Used on a long airgun.

It works.

Efficient, consistent with the description and use. Used on a bicycle and a metal replica of a Beretta.

A very cool idea, with lots of equipment there is always a scratch, which doesn't have to be permanent. Easy to use, I managed as an amateur, now I'm a pro. First, the ugly scratch disappears, second, rust doesn't attack.

Fulfills its purpose.

You need to apply several times, but I managed to cover up a scratch on the factory bluing. Rather for repairing smaller damages.
