steel is real... there you go...

as for anodizing... Go for it... I would caution you against doing it yourself.
The process involves electricity and acid. Too much acidity and you might run the risk of wearing down your threading, or exposing minute cracks in the welding.

I used to DIY aluminum paintball guns... the dye never came out as bold as I wanted it to and I actually made some air ports larger in the process from the acidity i believe.
