Hello good folks in the Lemmy Thinkpad community!

I have recently built a T420 from parts. Things have been running well. Since it's mostly from scraps, it's far from perfect, but it works.

One of my pet peeves is some discoloration along the edges and corners of the top cover. I am guessing this is the part where the paint got worn off from bumps and frictions. Is there a way to restore it? I honestly don't care about the rubberized coating, but having that consistent matte black would be really great.

I was thinking of that plastic model paint. Would it work well?

Also, the back part of magnesium chassis that's supposed to be painted black seems to have its bare color exposed.
