I'm planning to grind/cut a little bit in the middle or inner part of this disc because it's hitting the disc adaptor I bought. But if I grind it to make it fit, it will get scratched. Since it's originally black, the scratches will show up as silver. What do you think is the best paint to use and best process, to make it look like the original stock paint again? I'm not gonna fully repaint the whole black inner area, I'm just gonna paint the scratched area after cutting it. Any suggestions? also I'm considering, if ill just use a Black Permanent Marker? or no? the last 3 photos (red disc, not mine, just got the photo from Facebook, he's same situation as me) shows the overlapping part of disc on the adaptor (same adaptor as mine), and the owner shows the process on how he cuts it, but he just cuts it without painting and it looks ugly.
