I've done this myself. A few years back my old computer case looking like shit with scratches and a bad looking silver color in the center of the front. I did some studying and you have to do this outside. I got some plastic spray paint. I then gave a couple coats of gloss black to that case. It was actually pretty rugged to surprisingly not scratching by laying the pieces on the floor. I believe it was an old compact tower and my family were telling my how much better it looked. Recommendation, I am a smoker so I washed it with dawn and water before painting. I've found dawn is the only cleaner to get smoke and bong residue off stuff easily. I then rinsed carefully, dried, then used alcohol "isopropyl" right before the painting time. You can recoat if I remember right in like 20 minutes but put it on really lightly as in barely so you don't get drips. I think I went to an auto parts store to buy it or a hardware store. You can likely get a can for like 5 or 10 bucks on amazon, and to refinish an old case instead of buying a new one for that money is awesome. Also if you can a flourescent green and black combo could make a case look super cool. I was broke as fuck back then so one can was my budget but some light painters tape or a great eye and you could make a sweet looking case. Also can be used on other stuff so just use your imagination.

Funny thing about the plastic paint, it sprays out like the paint for cars that is attracted to ions so it just sticks. You can sand it but it goes on so smooth. If you did I would recommend a super high grit like a 1000 or more. This stuff was made for plastic or computer coatings because regular paint would peel off unless like you said you went to bare metal. The most I would do is fill gouges and deep scratches and then sand down the filler. This stuff I used coated like a factory paint job but without sanding or baking.

Yeah, for plastics (bezels and the like) I'd typically only very lightly abrade it with high grit paper, and even then only in those situations where it's had some sort of pernicious finishing applied to it. Cleaning is more important.

I suppose as an addendum to this - it's important to use the right paint for the material you're working with.

baking

This brings back a memory. It starts with a client asking about powder coating, and ends with working at three thirty in the morning on a Sunday. Fun, as the philosophers say.

I remembered the paint I used was Krylon plastic spray paint. Awesome shit and worth every penny. That case finish didn't have a scratch even 2 years later when I got my new computer. I would use this paint as a paint and a prime also because it sticks so well to plastic coating like cases and monitors. I would then use a regular spray paint for colors the plastic paint does not come in for trim and other decoration or if you wanted some cool masked logo work or skull and crossbones mattering what your taste was.
