If you google how to carefully and professionally do this, you will find a real answer. Here? No. We are all learning students in the sea of adventures we call "life". So instead, we will do it the hard way.
Grab your primer and spray the plate, then wait for how long it should take to become ready, which should be written on the can. Get some coffee, watch something cool. It's finished? Good. Now, slowly spray the black on the rustications we made. Clean off the cutting edge with sanding paper.
To dye the wood, get some leather dye and some alcohol, mix them 1/1. Wipe the wood and burn the liquid off with a lighter. Hand caught on fire? You dropped the alcohol and house started to burn? Half of the forest next to your house got burnt and the authorities are calling it the worst local forest fire in 20 years? We all have been there.
Keep wiping and burning for like 10-15 times which after the dye should have been set. Put it on a rack.
Congratulations. We are partially done! We shall still keep on going though. Because you know, why not?
