see if you can get a white primer. I know gaming primers can be a little expensive, but something like white scar from GW would work. Or you could use gray seer and drybrush a brighter white. Then thin down some nuln oil and coat it, i find it works well. painting white over black is so difficult

I def think spraying in white works better. Wanted to give white on black a try and not super fond of it so going back to black on white. I have an idea I wanna give a try so we’ll see how that goes!
