So I had a carpenter ghetto mod the midplate of my Phanteks Enthoo Evolv ATX (to fit a 280mm rad) and the PCI slots grill (to vertically mount my GPU). It turned out "ok" but there were some scratches (metal exposed) that I want to remedy. What is the best thing to do with these scratches? I figure I can use touch-up paints for cars or spray paints, whichever is easier and a closer match to the original color. The official color of the case is "Satin Black".

Here are some pics of what I mean:





P.S. I have zero confidence in myself in doing case mods but if I can get away with doing a little touch-up paint myself then I'm all for it.
