kirk123兄,小弟用五金舖買Blue鐵用藥水,Blue嘅係Nova鋼件,班點和花點如上圖
thank you!!
Did u use copper to brush it after each application of
bluing?
Steel
bluing needs 4-5 times application.
Friendly reminder: running water is necessary after each application and dry by cloth.
Your
bluing part should silver in color by sand paper.#400 & #800 respectively.
