Quick Bluing Solution (250 mL) - Brush and Immersion Application - Gun Bluing

I used other products before that were not convincing but this one is super easy to use and gets you great results in no time. Will buy again!

Painting only gives a deep blue, but immersion gives a nice black. At least on mild steel.

Great item and fast delivery. Highly recommended

Wow amazing, turned the barrel on my bsa ultra back to a nice black colour, easy to use

It does the job

while finished blued metal looks good, the blueing doesn't last. Easy wipes out, easy rusting althought I made a total of 12 applies following the instructions. I'm very dissapointed, now I'll have to do it again. The 2 star ratting is only for handling and shipping service which are excellent.

l tryed it for 3 days. nothing turned blue or black, l made shaw all was clean l even clean the area with white spirit, wast of money.
