So my goal is to etch a couple things into the blade holder of the saber and for right now it's certain that the main part will be a tri-force for the etching so not too much. However the bladeholder is powdercoated as well so this confused me somewhat on if and how it can be done.

I have looked everywhere on the web and in the forums about etching and have found mostly about muratic acid or hydrochloric acid mixed with hydrogen peroxide. I havn't had a clear understanding of the electric method yet. Even a link to somewhere is very helpful.

Does anyone have any preferences or experience with a good form of etching and maybe some instructions for any of these or your method? i'm not looking to spend a huge amount to do this and any insight would be very helpful.
