Ok, my Alpha Omega project is at a stage I can break away and complete this project now.
Sanded down the case front and resprayed in black, as had some imperfections on the previous spray job. This caused some crinkling on the paint job, so after leaving it for quite a while, left the case to completely dry. Just resanded again, and applied more spray paint, hopefully this time i'll get a good finish and can complete this project.
PS - decided to also post this project in my forum too, no reason not to on reflection and will be seen by more people that way.
