TLDR: I wouldn't do it.
STFU I wanna do this: Use crepe tape and wrap around the switch housings at the very edge to the plate thoroughly
, crimple close at their top, stick something in the holes and openings of the plate. Use Qtips and Isopropanol to degrease and clean the Plate thoroughly. Thin, crossed strokes, paint cloudish with distance and a lot of strokes from different sides - you definitely don't want liquid paint on the plate. GL.
Paint requires open surfaces to stick permanently. Sanding the plate would be adequate work prep, also cleaning with Isopropanol to degrease after that of course. Which require the switches to be removed. Solvents of the paint may harm the PCB plastic/coating under the plate maybe resulting in unwanted operation. So better remove it too. It's also hard to paint thin gaps evenly when you can't reach them and have to be careful not to overapply. The MX switch has a gap between upper and lower housing too, right where it sits on the plate. The most likely entry point for paint and solvents is the gap where the Diodes are located, not the round hole on the top but the opening underneath it.
Bottom line: I'm not the best in soldering too, but I would at least try to remove all the switches that can be done easily to make painting easier, be able to do at least some work prep, and therefore gain a more durable result.
