Hello

Has anyone used a chemical blacking kit on nut and bolts?

Haven’t had a go myself but have seen lots of views / threads on airgun forums. The executive summary is:

1) Don’t waste your time with cold bluing, it is rubbish.
2) Rust bluing gives slightly better results.
3) Follow the instructions to the absolute letter, otherwise you are doomed.
4) Get everything involved as clean as possible - any surface contaminants and you are doomed.
