Things I liked:

Ease of use. Reblueing is all about preparation. More time is spent to ready parts than to apply the blue. Follow the bottle directions

Things I would have changed:

This 3oz bottle should have a swab attached to the lid for larger projects. Using a Q-tip per directions is fine for smaller parts, but a 3oz bottle could do 3 rifle barrels.

What others should know:

Check You Tube for hints and preparation of metal, wear proper latex gloves thru out the whole application, and reapply to get an almost black hue. Follow the directions on the bottle, multiple applications only takes about 15-20 min. but when you get it where you like it, soak in a penetrating gun oil overnight. I lightly used 0000 steel wool between coats, and all parts came out perfect like factory finish. Very satisfied with results.

Things I liked:

I tried this on a raggedy old crosman 130. I got as good a result as if I had used rubbing alcohol. Basically nothing happened other than I got the metal wet.

Things I would have changed:

Make it actually work.

What others should know:

Not sure what happened axactly but this stuff did nothing on the gun I tried it on.

  • Francois from USA asked:

    Got quite a bit of rust on a RWS Magnum rifle corroded by salt air in a house hit by hurricane Maria. YouTube says to rub with copper mesh sponge. Will this product then reapply a protective blue?
