hello i am looking for a way to get a matte black finish as i am trying to make a clone of the mk42 heat bed and all the other methods i have seen have created a glossy finish which i don't want. So is there anyway for a diyer to get a matte black finish on a pcb

 

Don't know how rugged it is but it is hard to get a more "mat finish" than you can get by using Vantablack
